David, this still has the bogus address_space operation in addition to
the vm_operation. page_mkwrite only fits into the vm_operations scheme,
so please remove the address_space op. Also the code will be smaller
and faster witout that indirection..

For the native case the new naming is stupid. The old ioctl_unlocked
made perfect sense while ioctl_native doesn't - after all ->ioctl is
native aswell. Also this still has the useless inode * paramater in
the method signature.

Andrew, could you please finally drop this one? It's not needed for
reiser4 operation at all just for some of their stranger debugging
features.

What about moving fs/Kconfig.reiser4 to fs/reiser4/Kconfig? This is
the logical place for it and makes dropping in a new version of the fs
easier.

Documentation shouldn't be in fs/FOO/doc but Documentation/filesystems/.

Here's a better and much simpler patch:

- add ->unlocked_ioctl method and a do_ioctl wrapper in ioctl.c so all
places calling ->ioctl get it.
- add ->compat_ioctl method and call it in compat_sys_ioctl before doing
the hash lookup for registered handlers.
- streamline compat_sys_ioctl and move the complex error reporting into
a function of it's own

Regarding the inode* parameter, the change to remove it would be trivial,
though I personally dont care and I didnt see anyone else comment on that.
Anyone?

that the kernel won't boot even with these fixes, I'm debugging that now

And apparently it's broken on NUMA. I couldn't find
generic_file_get/set_policy in my tree, which builds with CONFIG_NUMA

When I was editing cdrom.h, I noticed that fs/isofs/compress.c was
recompiled. This patch removes the useless #include that caused the
unnecessary recompilation.

This patch removes an unused variable in the synaptics_data struct and
deletes a no longer helpful comment. I don't think this has been used
since the very first synaptics kernel patch I submitted that did all
processing in kernel space instead of delegating most of it to the X
server.

and then it goes into an infinite loop that writes some garbage to the

On a UP AMD64 it boots, but then it does not work appropriately (eg. at KDE
startup the box hangs for a while and I get the message like "The process for
the file protocol has terminated unexpectedly" and desktop icons are not
displayed, and I get a "cpu overload" message from arts etc.).

Please let me know if you need more information.

That's not the problem, since function and definition are in the same
module.

You didn't send your .config, but looking at the code it seems
CONFIG_PM=n was the culprit.

As a workaround, it should work after enabling the following option:
Power management options (ACPI, APM)
Power Management support

This is only a workaround, I've Cc'ed the ALSA maintainers for a real
fix.

First of all thanks for your report.
You didn't send the exact error mesage.
I'm able to reproduce the following in 2.6.10-rc3-mm1:

wrt. necessity, it's quite handy: check out the 2.6.10 changelog, almost
all preemption bugs wrt. smp_processor_id() were found this way.

what precisely is the 'mess' you are referring to?

is it the way the include file falls back to the original
smp_processor_id() definition if an arch doesnt define
__smp_processor_id()? I could get rid of that and just require every
arch to define __smp_processor_id().

or is it the addition of _smp_processor_id() as a way to signal 'this
smp_processor_id() call in a preemptible region is fine, trust me'? We
could do smp_processor_id_preempt() or some other name - any better
suggestions?

relying on that is quite futile. E.g. in the block IO code it needed 3-4
iterations even after the first instance was found to get all the cases
right. There are functions that are always called from under a lock then
some unlocked call happens and we've got trouble. Often the bug is some
very rare and obscure corruption of a statistics value, nobody really
notices that.

by today i think we've identified most of the places that can safely do
smp_processor_id() in a preemptible section (in x86 and x64) - it's only
around 3% of the total smp_processor_id() use. I'd rather allow these
exceptions and flag new exceptions as they get added - they are added at
least an order of magnitude more rarely than smp_processor_id() gets
added.

I'd just kill the debug check and rely on the eye of the review to not

let new users of smp_processor_id slip in.

I also tried it on an AMD64 system (3500+ on A8V Deluxe) and did not
observe any anomalies, but I am using Gnome, not KDE.

I saw a message that latency tests were wanted, but I don't normally have
a workload in which this can be observed. Perhaps someone could provide a
suggestion? I did try some dvd-burning sessions. Subjectively speaking,
there didn't seem to be any improvement over 2.6.10, and it may have been
a bit worse.

I suspect it is fixed by Bill Irwin's patch from the

Now I'm not seeing anything wrong either, so it must have been accidental. I
suspect that the problem was with artsd.

Yes, it's because of lack of #ifdef CONFIG_PM in ac97_patch.c.
It was already fixed in the linux-sound bk tree.

That's not right either. Filesystems really shouldn't be overloading the
vm_ops on memory mappings (as has been made clear to me) and the VM low-level
paging routines shouldn't be touching a_ops (as has also been made clear to
me). I also have other reasons I don't want to have ordinary files with
specialised vm_ops.

I suppose I could try and build a little knowledge about fscache into the
VM... that might be reasonable.

Remember also that your change is going to affect NFS too eventually, assuming
NFS caching support ends up being done this way. It may also affect other
filesystems, such as SMB/CIFS and Coda eventually should they partake of
fscache services too.

yes, they should. And various filesystems do.

Christoph, what else do you especially object against?

[Mark_H_...@raytheon.com]

After booting with 2.6.10-mm1, I get the following message on the serial
console (last message seen):

PCI: 0000:00:0b.0 has unsupported PM cap regs version (1)

For reference, lspci shows that device is
00:0b.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)

I notice there is a relatively recent patch to add this message.
http://article.gmane.org/gmane.linux.kernel/263974

However, my .config includes

#
# Power management options (ACPI, APM)
#
# CONFIG_PM is not set

which should disable all power management related processing.

[1] Should the code generating the warning be active without CONFIG_PM
being set?

[2] Can you explain why the message is generated (why not silently ignore
the older hardware) or is there something in an init script (I am using
Fedora Core 2) that [incorrectly] assumes power management is available to
cause the message to be printed?

this one I don't particularly object, but I'm not sure it's really
the right thing to do. Can you post it with a detailed description
to linux-mm so we can kick off discussion?

The other thing I'm totally oposed to was the per-sb kobject patch,
but I can't find that in current -mm anymore.

This patch adds an API to reserve some number of pages for exclusive use
of calling thread. This is necessary to support operations that cannot
tolerate memory allocation failures in the middle (reiser4 uses this API
to not have to undo complex uncompleted (due to ENOMEM) filesystem tree
modifications).

Implementation is simple: reserved pages are stored in a list hanging
off calling task_struct. Caller is to manually release unused pages.

This API is supposed to be used for small reservation (no more than few
dozens of pages).

Looking forward for advices on how to do that better/properly
Thanks

This will end up reserving more pages than were asked for, if
current->private_pages_count is non-zero. Deliberate?

this is a completely useless wrapper that doesn't buy anything.

Can probably be written much simpler as:

int perthread_pages_reserve(int nrpages, int gfp)
{
LIST_HEAD(accumulator);
int i;

list_splice_init(&current->private_pages, &accumulator);

Now the big question is, what's synchronizing access to
current->private_pages?

Would be much more readable with the error condition handling at the

Would be written much cleaner with a single return statement and the
comment above the function, ala:

/*

You should at least move the !in_interrupt() condition out here.

Umm, it's obviously correct as we're thread-local. Objection taken back :)

I hope this has not been extensively discussed yet, and I missed the
thread but, does everybody think this is a good thing?

This seems like a very asymmetrical behavior. If the code explicitly
reserves pages, it should explicitly use them, or it will become
impossible to track down who is using what (not to mention that this
will slow down every regular user of __alloc_pages, even if it is just
for a quick test).

Why are there specialized functions to reserve the pages, but then they
are used through the standard __alloc_pages interface?

At the very least this test should be moved to the very beginning of the
function. It is of no use to calculate "can_try_harder" before running
this code if it will use a reserved page.

Having a specialized function to get the reserved pages, would also make
the logic in "perthread_pages_reserve" more clear (i.e., that comment
would become unnecessary), and lose the test to "in_interrupt()" in
"perthread_pages_alloc", if I'm reading this correctly.

Safe without locks so long as there is no other way to get at another

I still don't get it why reiserfs can't put the preallocated
pool somewhere private like all other users who do similar things
do too (and yes there are quite a lot of subsystems who do
preallocation)

Why pollute task_struct for this?

That seems to be the whole point of the patch, as that way it'll serve

all sub-allocators or kernel function called by the user. Without this
behaviour the caller could have simply used a mempool.

Yes. This is to make modular usage possible, so that

perthread_pages_reserve(nrpages, gfp_mask);

/* call some other code... */

perthread_pages_release(unused_pages);

works correctly if "some other code" does per-thread reservations
too.

I disagree. Patch introduces explicit API

int perthread_pages_reserve(int nrpages, int gfp);
void perthread_pages_release(int nrpages);
int perthread_pages_count(void);

sufficient to create and use per-thread reservations. Using
current->private_pages_count directly

- makes API less uniform, not contained within single namespace
(perthread_pages_*), and worse,

Completely disagreed, hiding all the details doesn't help for such
trivial access, it's just obsfucating things.

But looking at it the API doesn't make sense at all. Number of pages
in the thread-pool is an internal implementation detail and no caller
must look at it - think about two callers, e.g. filesystem and iscsi
initiator using it in the same thread.

That's the whole idea behind this patch: at the beginning of "atomic"
operation, some number of pages is reserved. As these pages are
available through page allocator, _all_ allocations done by atomic
operation will use reserved pages transparently. For example:

perthread_pages_reserve(nr, GFP_KERNEL);

foo()->

bar()->

page = find_or_create_page(some_mapping, ...);

perthread_pages_release(unused_pages);

find_or_create() pages will use pages reserved for this thread and,
hence, is guaranteed to succeed (given correct reservation).

Alternative is to pass some sort of handle all the way down to actual
calls to allocator, and to modify all generic code to use reservations.

Nikita.

I don't see how this can work.

/* make conservative estimation... */
perthread_pages_reserve(100, GFP_KERNEL);

/* actually, use only 10 pages during atomic operation */

/* want to release remaining 90 pages... */
perthread_pages_release(???);

Can you elaborate how to calculate number of pages that has to be
released?

That's a good question actually, and it's true for the original
version aswell if we want (and to make the API useful we must) make
it useable for multiple callers in the same thread.

Assuming the callers strictly nest we can indeed just go back to the
orininal count, maybe with an API like:

int perthread_pages_reserve(unsigned int nrpages, unsigned int gfp_mask);

void perthread_pages_release(unsigned int nrpages_goal);

unsigned int old_nr_pages;

...

old_nr_pages = perthread_pages_reserve(100, GFP_KERNEL);

...

perthread_pages_release(old_nr_pages);

Maybe I'm being thick, but I don't see how you can protect the reservation
of an outer reserver in the above way:

perthread_pages_reserve(10);
... /* current->private_pages_count = 10 */
perthread_pages_reserve(10) /* private_pages_count = 20 */
use 5 pages /* private_pages_count = 15 */
perthread_pages_release(5);

But how does the caller come up with the final "5"?

Seems better to me if prethread_pages_reserve() were to return the initial
value of private_pages_count, so the caller can do:

old = perthread_pages_reserve(10);
use 5 pages
perthread_pages_release(old);

or whatever.

That kinda stinks too in a way, because both the outer and the inner
callers need to overallocate pages on behalf of the worst case user in some
deep call stack.

And the whole idea is pretty flaky really - how can one precalculate how
much memory an arbitrary md-on-dm-on-loop-on-md-on-NBD stack will want to
use? It really would be better if we could drop the whole patch and make
reiser4 behave more sanely when its writepage is called with for_reclaim=1.

Or just preallocate into a private array.

/* do something that consumes reservation */

Reiser4 doesn't use this for ->writepage(), by the way. This is used by
tree balancing code to assure that balancing cannot get -ENOMEM in the
middle of tree modification, because undo is _so_ very complicated.

Oh. And that involves performing I/O, yes?

Why does the filesystem risk going oom during the rebalance anyway? Is it
doing atomic allocations?

Yes, balancing may read tree or bitmap nodes from the disk.

No, just __alloc_pages(GFP_KERNEL, 0, ...) returns NULL. When this
happens, the only thing balancing can do is to panic.

__alloc_pages(GFP_KERNEL, ...) doesn't return NULL. It'll either succeed
or never return ;) That behaviour may change at any time of course, but it
does make me wonder why we're bothering with this at all. Maybe it's
because of the possibility of a GFP_IO failure under your feet or
something?

What happens if reiser4 simply doesn't use this code?

If we introduce this mechanism, people will end up using it all over the
place. Probably we could remove radix_tree_preload(), which is the only
similar code I can I can immediately think of.

Page reservation is not a bad thing per-se, but it does need serious
thought.

How does reiser4 end up deciding how many pages to reserve? Gross
overkill?

Hmm... it used to, when I wrote that code.

This is what happens:

- we start inserting new item into balanced tree,

- lock nodes on the leaf level and modify them

- go to the parent level

- lock nodes on the parent level and modify them. This may require
allocating new nodes. If allocation fails---we have to panic, because
tree is in inconsistent state and there is no roll-back; if allocation
hangs forever---deadlock is on its way, because we are still keeping
locks on nodes on the leaf level.

At the time I tested it, it panicked after getting NULL from
__alloc_pages(). With current `do_retry' logic in __alloc_pages() it
will deadlock, I guess.

Worst-case behavior of tree algorithms is well-known. Yes it's overkill.

And still does, if OOM decides to kill _your_ task: OOM sets PF_MEMDIE,
and then you don't get to go the retry route at all:

/* This allocation should allow future memory freeing. */
if ((p->flags & (PF_MEMALLOC | PF_MEMDIE)) && !in_interrupt()) {
/* go through the zonelist yet again, ignoring mins */
for (i = 0; (z = zones[i]) != NULL; i++) {
page = buffered_rmqueue(z, order, gfp_mask);
if (page)
goto got_pg;
}
goto nopage;
}
....
nopage:
....
return NULL;

Whenever scheme comes up I dont think the current check in __alloc_pages() is
any good:

if (order == 0) {
page = perthread_pages_alloc();
if (page != NULL)
return page;
}

Two things:

- all instances of an allocator from the current thread will eat from the perthread
reserves, you probably want only a few special allocations to eat from the reserves?
Thing is its not really a reservation intended for emergency situations,
rather a "generic per-thread pool" the way things are now.

- its a real fast path, we're adding quite some instructions there which are only
used by reiserfs now.

I think in a "final" implementation emergency allocations should be explicitly stated
as such by the callers ?

I believe the code is attempting to make sure the device is properly powered

Please don't. A system with this Promise 20269 card in it hangs without this
patch, I can see the splat happen with a PCI analyser.

The function being altered is almost certainly _wrong_ for non-PM-version-2
cards, but I don't have an old enough PCI spec to check.

A better solution would be to drop the level of the printk() to KERN_DEBUG or
to delete it entirely, assuming the patch otherwise works for Mark.

ok, we will change reiser4 to keep its pool of preallocated pages
privately as Andi suggested. This will require to have
reiser4_find_or_create_page which will do what find_or_create_page does
plus get a page from the list of preallocated pages if alloc_page
returns NULL.

So, currently, reiser4 depends on the core patches listed below. Would
you please look over them and let us know which look reasonable and
which are to be eliminated.

reiser4-sb_sync_inodes.patch
This patch adds new operation (sync_inodes) to struct super_operations.
This operation allows a filesystem to writeout dirty pages not
necessarily on per-inode basis. Default implementation of this operation
is sync_sb_inodes.

reiser4-allow-drop_inode-implementation.patch
This EXPORT_SYMBOL-s inodes_stat, generic_forget_inode, destroy_inode
and wake_up_inode which are needed to implement drop_inode.
reiser4 implements function similar to generic_delete_inode to be able
to truncate inode pages together with metadata destroying in
reiser4_delete_inode whereas generic_delete_inode first truncates pages
and then calls foofs_delete_inode.

reiser4-truncate_inode_pages_range.patch
This patch makes truncate_inode_pages_range from truncate_inode_pages.
truncate_inode_pages_range can truncate only pages which fall into
specified range. truncate_inode_pages which trucates all pages starting
from specified offset is made a one liner which calls
truncate_inode_pages_range.

reiser4-rcu-barrier.patch
This patch introduces a new interface - rcu_barrier() which waits until
all the RCUs queued until this call have been completed.
This patch is by Dipankar Sarma <dipa...@in.ibm.com>

reiser4-reget-page-mapping.patch
This patch allows to remove page from page cache in foofs_releasepage.

reiser4-radix_tree_lookup_slot.patch
This patch extents radxi tree API with a function which returns pointer
to found item within the tree.

reiser4-export-remove_from_page_cache.patch
reiser4-export-page_cache_readahead.patch
reiser4-export-pagevec-funcs.patch
reiser4-export-radix_tree_preload.patch
reiser4-export-find_get_pages.patch
reiser4-export-generic_sync_sb_inodes.patch
The above patches EXPORT_SYMBOL several functions. Others may find it
useful if they were exported.

reiser4-export-inode_lock.patch
Reiser4 used to manipulate with super block inode lists so it needs
inode_lock exported.
We are working now to not need this. But quite many things are based on
it. Is there any chance to have it included?

Thanks

Hi Vladimir,

a general request:

If you add new EXPORT_SYMBOL's, I'd strongly prefer them being
EXPORT_SYMBOL_GPL's unless there's a very good reason for an
EXPORT_SYMBOL.

Not okay. I though I explained you how to do it instead already?

No idea, but if Dipankar things it's okay it probably is.

probably ok, Andrew?

Idea is okay, implementation needs work:

__lookup_slot should be called radix_tree_lookup_slot and exported direcly.

radix_tree_lookup should be an inlined wrapper in the header, and kill
the != NULL comparims, it's superflous:

static inline void *radix_tree_lookup(struct radix_tree_root *root,
unsigned long index)
{
void **slot = radix_tree_lookup_slot(root, index);
return slot ? *slot : NULL;
}

> reiser4-export-remove_from_page_cache.patch

Probably okay, but why do you need both remove_from_page_cache
and __remove_from_page_cache?

> reiser4-export-page_cache_readahead.patch

ok

> reiser4-export-pagevec-funcs.patch

ok

> reiser4-export-radix_tree_preload.patch

this one is nasty. not your fault though, but why do we even
have global radix-tree preloads instead of pools. What do you
need it for?

> reiser4-export-find_get_pages.patch

Why don't you use pagevecs instead?

> reiser4-export-generic_sync_sb_inodes.patch

Can't find this one in current -mm

No. Modules must not look at inode_lock, it's far too much of an
implementation detail.
