Fixed by commit 494de90098784b8e2797598cefdd34188884ec2e: "Do not
overwrite nr_zones on !NUMA when initialising zlcache_ptr" by Mel.

I wonder if this one could be related. The 'nr_zones' overwriting bug
would result in kswapd not reclaiming any memory asynchronously, so the
kernel would basically be constantly under a low-memory situation, and
processes would be forced to do synchronous reclaim.

That, in turn, could easily explain laggy operation, especially if it is
something bigger that needs to allocate new memory (not that I know if X
dimming needs to, but I could imagine that it does some double buffering
or whatever).

This really doesn't sound like low memory, but the CONFIG_NUMA thing is
intriguing, since again, the 'nr_zones' thing depended on that. It would
break 'balance_pgdat()' entirely, and maybe some balancing operation can
get confused even before you actually run out of memory

Unlikely, but worth re-testing.

This one is the same thing that is reported as unresolved, and no, I don't
think that existing patch was ever really tested to fix anything. Paul?

I suspect SRCU will need to be simply marked BROKEN for now, because
nobody knows what the problem Alexey sees is. Apparently it's been seen by
a few other people too.

Oh ... it was reported against 2.6.26-rc1, so the fix is actually
crrently queued for scsi-misc in my internal test rig. However, the
reason for the long QA is that there's a potential danger to the fix
which is clearing the buffer from the reported length to the actual
length will break a SCSI card that misreports the returned length. It
seems to be OK on my esoteric SCSI card collection, so I'll push it out
to scsi-rc-fixes. However, I think it still wants to run in linux-next
for a few days to see if anyone else can turn up a problem.

The true issue, of course, is that we won't see a problem until the
2.6.26 release because the hardware that triggers it isn't in the set
we're testing with. A less risky fix for 2.6.26-rc9 might be to move
the clearing into the affected subsystem (usbstorage).

I'm not sure it's directly related to SRCU - it can change timings and
freeing patterns enough to tickle other bugs. Since Alexey Dobriyan has
reported it - are perhaps namespaces in use during this stress-test?
Maybe it's some namespaces related bug that is more easily reproduced
under SRCU - namespaces is not a commonly tested feature.

Also, i've been running rcutorture stress-tests on a number of
test-systems ever since this got reported (and they are running
currently as well) and cannot see it - neither could Paul reproduce it.

( and Paul is very good in producing RCU related problems - he's
triggered and fixed many RCU related problems that no-one else saw
before. )

Also, in the next couple of days I'll be closing the bugs the reporters of
which have been totally unresponsive.

I'll post an updated report after that.

If no action by us gets combined with automated weekly emails then
no responses to the latter is not an unexpected event.

Such a submitter might be perfectly responsive to actual work on a bug
while really pissed off by getting the bug closed.

Look e.g. at #10865 that had a 1 month gap in submitter responses,
but the actual problem is that noone of us ever bothered to look at
this Oops...

I just did a run through all open 2.6.26-rc regressions, and I did not
find a single one where we seem to be waiting for some time for an
answer of the submitter. [1]

The report is 46 days old and the reporter has been sent a request to confirm
the presence of the problem every week. Since he hasn't responded to any
of those requests, I assume we're not going to hear from him. Thus, it's not
useful to track this any more.

Andrew Morton also never bothered to answer the automated emails you
sent him regarding the regression he reported...

Humans react differently to programs than to humans interacting with
them, and tons of automated mails without any actual efforts by humans
can easily be considered a non-friendly act.

But for this bug I now found the commit that fixed it back in May.

Is there any specific reason why your automated emails only go to the
submitters but not to the maintainers of the code in question? If you
had Cc'ed Kyle once during the last 46 days he might have remembered
that he already fixed this bug...

Adrian - please just stop this.

*DEVELOPERS* are human too.

And if you cannot accept the fact that developers need feedback as well as
reporters - a simple "is it still a problem" report - then why the *hell*
do you then talk about reporters being human?

> But for this bug I now found the commit that fixed it back in May.

Exactly. A _lot_ of problems are fixed independently of a specific
bug-report, either because others reported the issue too (and people
didn't necessarily even realize that it was the same problem), or because
a developer found it independently and fixed it.

Is there any specific reason that you have been complaining about this for
A HELL OF A LONG TIME, without ever actually listening to what people like
me tell you, over and over and over again?

And no, this email wasn't autogenerated. But you seem to never react to
this.

Bug-reports absolutely *have* to be closed if they don't get minimal
feedback, including just a "it's still a problem".

Just accept it, Adrian.

Yes, there is. We'd have to add special annotations to bug reports for that
and I'm not always sure which list/maintainer combination is appropriate.

He might have looked at the regression reports just as well.

BTW, the automated emails I'm sending are to let the reporters know that I'm
interested in the current status of the bug. They are free not to reply to
them, but in that case I assume they don't really care whether or not I'm
tracking the bugs they reported.
