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.

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).

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 -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
