Subject2.5.74-mm1


ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.74/2.5.74-mm1/

. Mainly a resync with various things and people. Plus a few fixlets.

. I dropped out a few patches which weren't really proving useful.

. Included Con's CPU scheduler changes. Feedback on the effectiveness of
this and the usual benchmarks would be interesting.

Changes to the CPU scheduler tend to cause surprising and subtle problems
in areas where you least expect it, and these do take a long time to
materialise. Alterations in there need to be made carefully and cautiously.
We shall see...
