 Frederic? Al? I assume this is some late fallout from the BKL removal
 ages ago.. It's the old filldir-vs-mmap crud, but normally it should
 be impossible to trigger because the inode for a directory should
 never be mmap'able, so we should never have the same i_mutex lock used
 for both mmap and for filldir protection.
 
 We saw some of that oddity long ago, I wonder if it's lockdep being
 confused about some inodes.



I think it has been there from the beginning. At least it was there before
the reiserfs bkl removal in .32.


Indeed the readdir - unmap/release inversion problem can not happen.
But Al said that can happen between write and release. (Although I don't see
where write takes the inode mutex).

He also highlighted the fact that reiserfs refcounting based on i_count
was totally broken.

He has a fix the whole in the vfs tree, in the for-next branch on commit
6c2bdaf089a3876226893fab00dd83596c465ad2
Fix reiserfs_file_release()

No more uses of the i_mutex on release after that, nor i_count, but a private
openers refcount and a tailpack mutex per reiserfs inode.

 This has I have a fix, will post it very soon. in the thread from
 Frederic, but I'm not seeing anything else. Frederic?



Right. In fact it wasn't a regression. The per task breakpoint reservation
design was broken from the beginning and this warning has revealed the
problem. This only touched perf, and it did since perf support breakpoints.
Fortunately ptrace wasn't concerned by this problem, even not by side effects
of this.

The fix is invasive as it's a rewrite of a (little) part of the breakpoint
reservation. And since the symptom is only a warning and also breakpoints
never released from the constraint table (just a counter, no memory leak),
the fix is headed for 2.6.36.

It is ready in tip:/perf/core:

http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=45a73372efe4a63f44aa2e1125d4a777c2fdc8d8

I think this ticket can be safely closed.

Thanks.

 This is a gcc-4.5 issue. Whether it's also something that we should
 change in the kernel is unclear, but at least as of now, the rule is
 that you cannot compile the kernel with gcc-4.5. No idea whether the
 compiler is just entirely broken, or whether it's just that it
 triggers something iffy by being overly clever.

 This seems to be partly a confusion about what load average is. It's
 not a CPU load, it's a system load average, and disk-wait processes
 count towards it. He has some problem with his CD-ROM, and it sounds
 like it might be hardware on the verge of going bad.

Can be put down to bad ramdisk settings  actual memory, its probably
not a regression.
I think it can be closed for now, i'll do some testing and see if
ramdisk should complain before letting such configuration go through.

 I'm not entirely sure if these RCU proving things should count as 
 regressions.

Generally not - and we've delayed at least one more complex (cgroups) fix to 
v2.6.36 because the patch itself was riskier than the warning.

Still most of the warning fixes turned out to be simple, so we merged the 
very-low-risk ones and right now we seem to be on top of them.

But in general the default rule is that we delay these fixes to v2.6.36.

 Sure, the option to enable RCU proving is new, but the things it reports 
 about generally are not new - and they are usually not even bugs in the 
 sense that they necessarily cause any real problems.
 
 That particular one is in the single-thread optimizated case for fget_light, 
 ie
 
 if (likely((atomic_read(files-count) == 1))) {
 file = fcheck_files(files, fd);
 
 where I think it should be entirely safe in all ways without any locking. So 
 I think it's a false positive too.

Yeah, it's a bit like with lockdep (and it's a bit like with compiler warning 
fixes): we had to punch through a large stack of false positives that 
accumulated in the past 10 years.

( Because real bugs eventually get fixed, while false positives always just
  accumulate. So almost by definition we always start with a very assymetric
  collection of warnings and a large stack of false positives. )

Having said that, it appears we got most of the false positives and are 
beginning to be in a more representative equilibrium now. If v2.6.35 isnt 
going to be warning-free then v2.6.36 certainly will be and new warnings will 
have a much higher likelyhood of being real (and new) bugs (not just 
accumulated false-positives).

 I don't think anybody noticed this one. Jesse?

Oh I hadn't seen that...  Enrico, can you bisect this issue?  It could
be some spurious hotplug events or possibly a stuck vblank interrupt...

 Dave, Jesse?

I haven't looked at the switchable graphics stuff, hopefully Dave has
an idea here.

 Fixed by commit f4985dc714d7.

 This has a butt-ugly suggested patch that certainly won't be applied.
 I saw the thread, but lost sight of it. Jesse, did that end up with
 some resolution?

I'll follow up with Yinghai, we were pretty clear about what we wanted
from that patch.

 Hmm. That one is the vt.c bug coupled with another problem, which in
 turn got opened as a separate bugzilla entry:
 
http://bugzilla.kernel.org/show_bug.cgi?id=16252
 
 which in turn then got closed. I dunno.

Yeah, this is weird.  Norbert, do you still see this?  Have you tried
to bisect it?

[Bug 14596] radeon DRI driver produces garbled console with KMS enabled on Thinkpad T42

2010-07-09 Thread bugzilla-daemon

--- Comment #11 from Egor Y. Egorov egorov_e...@bk.ru  2010-07-09 17:45:24 ---
Similar problem on 2.6.34 (gentoo- and zen-kernel).
To my PC connected monitor (DVI-0) and TV (S-video).
Monitor display is ok.
TV display fine with radeon.modeset-0
With radeon.modeset=1 screen has horizontal line (like
http://bugs.freedesktop.org/show_bug.cgi?id=26915), but patch
http://bugs.freedesktop.org/attachment.cgi?id=33809action=edit dont fix it.

  This has I have a fix, will post it very soon. in the thread from
  Frederic, but I'm not seeing anything else. Frederic?
 
 
 
 Right. In fact it wasn't a regression. The per task breakpoint reservation
 design was broken from the beginning and this warning has revealed the
 problem. This only touched perf, and it did since perf support breakpoints.
 Fortunately ptrace wasn't concerned by this problem, even not by side effects
 of this.
 
 The fix is invasive as it's a rewrite of a (little) part of the breakpoint
 reservation. And since the symptom is only a warning and also breakpoints
 never released from the constraint table (just a counter, no memory leak),
 the fix is headed for 2.6.36.
 
 It is ready in tip:/perf/core:
 
 http://git.kernel.org/?p=linux/kernel/git/tip/linux-2.6-tip.git;a=commitdiff;h=45a73372efe4a63f44aa2e1125d4a777c2fdc8d8
 
 I think this ticket can be safely closed.

OK, closing.

Rafael
