[GIT PULL V2] Squashfs updates for 2.6.34-rc1
Phillip Lougher
Please consider pulling the following revised Squashfs update for 2.6.34-rc1.
I have removed all the lzma/bunzip2/inflate/lzo code changes (which as far as I
know were the blocking issue previously).
What remains in the pull request is a clean-up/refactoring of the zlib
wrapper code, outline knowledge of lzma/lzo compressed filesystems (unsupported,
but it gives users an understandable error message when they try to mount them),
and some trivial code tidying.
Please pull.
Thanks
Phillip

I saw that Linus pulled this and some earlier related packages. I am not sure
if I should expect working lzma squashfs in 2.6.34 right now, or if I still
need to wait a bit?
P.S.
Thanks for working on this!

I believe I correctly tested this and found that I indeed do have to wait
for more to happen for lzma support. But it didn't seem to cause a problem
for zlib support.

I have a large (500M) squashfs root filesystem, which is mounted from
initramfs.
After mounting I can chroot into it.
With 2.6.34-rc1 seems that some directories are corrupted - e.g. /lib
may have only files up to libnss (alphabetically), or that some binaries
are not executing - because I see they are all NULLs on read, e.t.c.
Basically - the root is not usable.
Replacing the fs/squashfs source dir with a 2.6.33's one fixes the
problem - so it is the new code issue...
