I don't know that this should be carried as a regression.
Yes, the code in question increases cross cpu wakeups, but that's the
entire point. If there is any overlap in execution larger than the cost
of running a scheduler on another core, that time can be converted to
throughput.
Tip AF_UNIX lmbench numbers show that throughput gain being realized,
TCP numbers below that (x) show what can be had for apps which do a lot
of what that microbenchmark does, given a tiny enabler patchlet.
*Local* Communication bandwidths in MB/s - bigger is better

(1. tip memory numbers are phase-of-moon anomaly.. irrelevant here)
(2. pipe numbers are only possible with pipe buffer increase patch in
tip. Often, pipes are truly synchronous, so waking cross CPU is small
loss. In tip, it's a win because of optimistic mutex spin.. context
switch cost is converted to throughput. That throughput gain also
cannot be had if you don't do the cross cpu wakeup to get the ball
rolling. The code in question is acting as enabler for spintex.)
So yeah, the code in question _will_ cause more cross CPU wakeups, and
it _may_ cost power. It may _save_ power by getting the job done more
efficiently. Dunno.
Regression? Depends on what you're measuring.

I have a set of patches to clear up the sysfs lockdep false positives.
http://lkml.org/lkml/2010/2/11/329
It requires sprinking a bunch of sysfs_attr_init on the few dynamically
allocated sysfs attributes, and I haven't found them all yet. Otherwise
it seems to be working well.
Greg should pick up those patches shortly and they should be appearing
in linux-next and then ultimately in 2.6.34.

Rafael J. Wysocki
OK, so I'm going to close this report as "documented", since this is
intentional behavior.
Thanks,

Great, I'm glad that these issues are being worked on.

We are taking care of it. It's actually two regressions.
One has a fix that seems to work, and I'm working on the other one,
trying to get that upstream before 2.6.33 gets released.
Please keep the ticket open for now.
Thanks.
