Subject: 2.4.24-ck1 updated
Date: Thu, 22 Jan 2004 22:39:37 -0500 [thread overview]
Message-ID: <1074829176.32641.5.camel@localhost> (raw)

The 2.4.24-ck1 patchset has been updated to fix a mis-merge that
affected batch scheduler performance. The patch-2.4.24-ck1.bz2 and
010-ckbase.diff.bz2 files have both been updated to include the fix.
I could have sworn that I triple-checked every line of the patchset, but
one line slipped through. In arch/i386/kernel/entry.S a call to
userspace_resched() was omitted. As a result, SCHED_BATCH tasks
monopolized the CPU and starved other interactive tasks.
The moral of the story is: Don't fall prey to merge-hypnosis. :)
-Eric
