From: Linus Torvalds <torvalds@...>
Subject: Linux 2.6.26-rc2
Date: May 12, 10:55 am 2008

About 45% architecture updates (counting the include files too), about 30%

drivers, and about 25% odds-and-ends. The odds-and-ends are mainly

Documentation, filesystems (mostly cifs) and core kernel (scheduler

updates etc).
The dirstat and shortlog is appended, because while not exactly tiny it

should still fit easily in the lkml size limits. And if you read the

shortlog and get the feeling that most of it is pretty boring small

details, you'd be right. There is little exciting there.
A fairly small part of it, but quite possibly the most noticeable one, is

how the semaphore changes impacted the BKL (the old "big kernel lock" that

is still used for some legacy code, for you non-core people out there),

which in the past had different versions ("regular", "preemptable").
A few months ago we dropped the regular BKL version, but in 2.6.25-rc1 we

then had performance (and then correctness) issues with the interaction

between the semaphore implementation and the preemptable BKL, so we're

back to the old regular version for now.
Let's see if anybody notices. It looks likely that some latency issues

have regressed since (cond_resched()), and we'll need to see what we can

do about that whole thing.

Hello Linus,
Sorry if it's my fault that I do not understand the above message

completely. But from the above it's not completely clear to me which

kernel versions (2.6.2?.? releases) are affected and which are not

affected by the performance and correctness issues due to the

interaction between the semaphore implementation and the preemptable

BKL. Can someone please be so kind to post the affected kernel

versions ? And whether or not this issue was triggered probably

depends on the CONFIG_... options with which the kernel was built ?
Bart.

No released kernels are affected. It's purely a matter that has happened

after 2.6.25. The semaphore simplifcation in -rc1 caused a huge

performance regression on some benchmarks, and the fix to that in turn

caused a semaphore correctness issue, so I just rolled back to the

original BKL code that doesn't have any of those interactions.
In a historical context, the issues involved would only have happened with

CONFIG_PREEMPT_BKL. That config option was made the only one in January,

and as a result of these issues, we effectively switched it off.
So you can *think* of the effect of the changes as having gone from

CONFIG_PREEMPT_BKL=y to CONFIG_PREEMPT_BKL=n, even though technically we

had removed the actual config option to let people choose (so the config

option has basically become a static code change).
We may end up having to re-instate the config option due to this.

Personally, I hope not. It would be nicer if we could just avoid

PREEMPT_BKL entirely. 
(To make things somewhat more confusing, some non-PREEMPT_BKL code has

then bitrotted since, so if can actually see latency issues, you might

want to try the patch here at the end of this email to see if it fixes

the worst of them. "cond_resched()" has regressed since the PREEMPT_BKL

config option went away).
