Yes, unless something in this area has changed from -rc4 to -rc5, this is

This is wasteful. :-)
Also, I hope we won't spit message every time allocation fail.

Whatever, patches welcome :)

> Also, I hope we won't spit message every time allocation fail.

We do. Your system is mostly hosed anyway, but feel free to rate limit
it or something.

The error handling in there is a bit dubious, if the alloc fails we just
return the old name, which we know is bogus. It should probably return
NULL and the calling code can check - same for fixup_name().

OK

Is anyone going to post a clean patch for that with a sign-off?

I added GFP_KERNEL to kstrdup to make the compile error go away:

fs/proc/proc_devtree.c: In function ‘unslash_name’:
fs/proc/proc_devtree.c:183: error: too few arguments to function ‘kstrdup’
make[2]: *** [fs/proc/proc_devtree.o] Error 1
make[1]: *** [fs/proc] Error 2
make: *** [fs] Error 2

And now 2.6.34-rc5 compiles and boots without the warning. Thanks! 
New dmesg and /proc/device-tree on:

  http://nerdbynature.de/bits/2.6.34-rc1/xlate_proc_name/

Alexey mentioned that this is "wasteful" - does it make the kernel slower? 
I have not done any performance tests, but I'd rather stick with the 
warning than make this Powerbook G4 any more slower :-\


Thanks again,

Cool, and we see:

Which is the one that needed fixing.

Maybe a little. It has to check every string to see if it contains a

which might make up the difference. But it's a one time fixup at boot,
so it's not going to be noticeable.

Never mind me - this is a harmless (but loud) overflow

FWIW, I hit that warning too when chasing the anon_vma regression. It
seems on certain workloads (for me it was several kvm guests) we're
close to max preemption depth.

Anyway, adding some more people to Cc.

Right, so my proposed solution to this is to make those locks
preemptible, but that's a large and unfinished patch-set.

As it is, its only a warning, nothing really serious should happen, but
the situation does suck.

I'm not sure if it's worth keeping that listed, though, as the problem is known
and won't be solved before .34 final.

OK to close as "will fix later"?

Don't know if this is still present, after reporting it here on the list,
I've been advised by Chr. Lameter to switch from slab to slub. I did, and
haven't seen this again.

So what are our options? We can revert the SLUB conversion patch for now 
but I still can't see what's wrong with it...

I haven't been able to reproduce this either on my Core 2 machine.

Yanmin, does something like this help on your machines? I'm thinking false 
sharing with some other per-CPU data structure that happens to be put in 
same percpu slot as struct kmem_cache_cpu...

I also don't know why. The original patch looks good.

Mostly, the regression exists on Nehalem machines. I suspect it's related to
hyper-threading machine.

>

A quick testing doesn't show any help.

I did a new testing. After the machine boots, I hot remove 8 hyper-threading cpu
which means last 8 are just cores. The regression between 2.6.33 and 2.6.34-rc becomes
small.

My opinion is we needn't revert the patch, but still keep an eye on it when testing other
new RC kernel releases. One reason is volanoMark and netperf have no such regression.
Is it ok?

OK, so does anyone know why hyper-threading would change things for
the per-CPU allocator?

So it's unlikely to be false sharing, I suppose.

We need to get this fixed. In my experience, it's pretty common that
slab regressions pop up only in one or few benchmarks. The problem is
likely to pop up in some real-world workload where it's even more
difficult to track down because basic CPU profiles don't pin-point the
problem.

Do we have some Intel CPU expert hanging around here that could
enlighten me of the effects of hyper-threading on CPU caching? I also
wonder why it's showing up with the new per-CPU allocator and not with
the homebrewn one we had in SLUB previously.

My wild speculation is that previously the cpu_slub structures of two
neighboring threads ended up on the same cacheline by accident thanks
to the back to back allocation.  W/ the percpu allocator, this no
longer would happen as the allocator groups percpu data together
per-cpu.

Thanks.

Yanmin, do we see a lot of remote frees for your hackbench run? IIRC,
it's the "deactivate_remote_frees" stat when CONFIG_SLAB_STATS is
enabled.

I'm not familiar with the details or scales here so please take
whatever I say with a grain of salt.  For hyperthreading configuration
I think operations don't have to be remote to be affected.  If the
data for cpu0 and cpu1 were on the same cache line, and cpu0 and cpu1
are occupying the same physical core thus sharing all the resources it
would benefit from the sharing whether any operation was remote or not
as it saves the physical processor one cache line.

Thanks.

Even if the cacheline is dirtied like in the struct kmem_cache_cpu case? 
If that's the case, don't we want the per-CPU allocator to support 
back to back allocation for cores that are in the same package?

Btw, I focused on remote frees initially before I understood what you 
actually meant and scetched the following untested patch to take advantage 
of the fact that struct kmem_cache_cpu doesn't fill a whole cache line. It 
tries amortize remote free costs by "queuing" objects. It would be 
interesting to see if it helps here (or in the other SLUB regressions like 
netperf and the famous Intel one).

If my hypothesis is the case, I don't think dirtying or not would
matter.  It's about two cpus sharing a cache line which usually is a
bad idea but in this case happens to be a good idea because the two
cpus sit on the same cache.

I think it's probably gonna be an over-engineering effort.  W/ percpu
allocator the rest of the cacheline would likely be occupied by
another percpu item for the cpu, so it's not really wasted.  It's just
used differently.  It would be good if we have a way to better pack
small hot ones (for the same cpu) into the same cachelines but I don't
think it would be wise to interleave stuff from different cpus.  It's
not like there's only single way to save a cacheline after all.

Thanks.

After runing the testing with 2.6.34-rc5:

After running testing against 2.6.33 kernel:

I remember with 2.6.34-rc1, the fast alloc/free are close to the one of 2.6.33.

Hasn't reproduced after many retries and I am not sure it can be called a 
regression, may be it's always been there, just not reproducible easily -

That doesn't look like related to the bkl removal.

In fact what I wonder is how we missed that before.

vfs_readdir() take the directory inode mutex
    |
    ------- copy_to_user() takes the mm->mmap_sem

sys_unmap() takes mm->mmap_sem
    |
    ------- reiserfs_file_release() takes inode mutex


The lock inversion can not happen as sys_getdents() can't be called
after the directory is closed.

I'm not sure what to do. Adding more people in Cc.

Please list these two similar regressions from 2.6.33 in the r600 DRM:

 * r600 CS checker rejects GL_DEPTH_TEST w/o depth buffer:
           https://bugs.freedesktop.org/show_bug.cgi?id=27571

 * r600 CS checker rejects narrow FBO renderbuffers:

Do you want to me to add them as one entry or as two separate bugs?

First one is userspace bug, i need to look into the second one.
ie we were lucky the hw didn't lockup without depth buffer and
depth test enabled.

As upstream doesn't consider the first to be a kernel issue, I guess you
should just list the second.

OK, if the failure is due to userspace is doing Very Bad Things(tm),
catching that seems reasonable.

Nevertheless, even if it happened by luck, the result was (ostensibly)
working programs that suddenly break once one "upgrades" to the latest
kernel.  If userspace can't be fixed before 2.6.34 is released, perhaps
a less cryptic log message would be appropriate?

I pushed fix into mesa for the depth issue i will look into the other
one today and likely push kernel fix.

At least the effects on b2c2-flexcop-pci are still valid, in linux-2.6
HEAD and linux-next (next-20100621).

Yes, the bug is still present in 2.6.34 and .35-rc3, but a tested patch is 
available, hopefully to be included in 2.6.35.

Thanks,
Christian.

BOFH excuse #302:

microelectronic Riemannian curved-space fault in write-only file system

2.6.35-rc3: Reported regressions 2.6.33 -> 2.6.34

[Rafael J. Wysocki]

[NOTES:
 * This report has been delayed, because I had to go through all of the
   entries and filter out the fixed ones, invalid ones etc.  Of course, I might
   have missed some, but hopefully not too many.
 * E-mail reports from the last 7 days are not included.]

This message contains a list of some post-2.6.33 regressions introduced before
2.6.34, for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved post-2.6.33 regressions, please let us know
either and we'll add them to the list.  Also, please let us know if any
of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

So, now we have two patches for slightly different issues?

* http://lkml.indiana.edu/hypermail/linux/kernel/1006.0/00137.html
  ...fixes the flexcop-pci.c driver.

* http://patchwork.ozlabs.org/patch/52978/
  ...fixes "some bogus firmwares include properties with "/" in their
  name". I'm not sure if this would make the flexcop-pci.c badness go 
  away too. 

Anyway, both patches are not upstream yet, but Michael mentioned that 
Grant Likely or Ben might push it eventually.

Thanks,
Christian.

On brief review, they look like completely different issues.  I doubt
the second patch will fix the flexcop-pci issue.  I'll pick up the
device tree patch, but the flexcop-pci patch should go in by the
v4l/dvb tree.

Yes, the latter patch dodges the issue with flexcop driver by simply
skipping the directory creation, but both patches should be applied IMO.
The former to fix the flexcop driver because we can trivially fix it,
the latter to solve problems with any generic bogus firmware.

I think we've crossed wires.  By second patch I mean the patch that
changes OF code.  That change has absolutely no bearing on the
flexcop-pci driver.  The patch to the flexcop-pci driver looks correct
to me, but it is completely unrelated to the OF badness.

The bug is still present in -rc6, but Michael Ellerman has a patch[0] 
which made the warning go away.

@Michael: will you post your patch with a Sign-Off, so that it can be 
          pushed into mainline?

Thanks,
Christian.

No, Benh and I decided it's better to just drop those properties all
together. But it's too late in this cycle for a patch like that just to
fix a warning - so we'll do that patch for 35.

2.6.34-rc2: Reported regressions from 2.6.33

[Rafael J. Wysocki]

[NOTES:
 * In this cycle the regressions reported by e-mail will only be put into the
   Bugzilla 1 week after they have been submitted, if not fixed in the
   meantime.  The reason is that some regressions are fixed in less than a
   week time and there's no point listing them.  [We also hope that people will 
   try to fix bugs faster to avoid being listed. ;-)]  If that works, we'll
   adopt it as a general rule.

 * All of the regressions reported by e-mail that are listed below have been
   put into the Bugzilla by Maciej, because I literally didn't have the time
   to do that (that's also why the summary reports are delayed).
   Thanks Maciej!]

This message contains a list of some regressions from 2.6.33,
for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved regressions from 2.6.33, please let us
know either and we'll add them to the list.  Also, please let us know
if any of the entries below are invalid.

to this message with CCs to the people involved in reporting and handling
the issue.
