Fans of Ingo Molnar's scheduler patch will be happy to learn that Linus has accepted it into the 2.5 development kernel with 2.5.2-pre10. In releasing his latest update, Ingo comments, "now that Linus has put the -D2 patch into the 2.5.2-pre10 kernel, the 2.5.2-pre10-E1 patch has become quite small :-)".

pre9:
 - Russell King: large ARM update
 - Adam Richter et al: more kdev_t updates

pre8:
 - Greg KH: USB updates
 - various: kdev_t updates

Subject: [patch] O(1) scheduler, -E1, 2.5.2-pre10, 2.4.17
Date: Tue, 8 Jan 2002 15:32:55 +0100 (CET)

this is the latest update of the O(1) scheduler:

	http://redhat.com/~mingo/O(1)-scheduler/sched-O1-2.5.2-pre10-E1.patch

        http://redhat.com/~mingo/O(1)-scheduler/sched-O1-2.4.17-E1.patch

now that Linus has put the -D2 patch into the 2.5.2-pre10 kernel, the
2.5.2-pre10-E1 patch has become quite small :-)

The patch compiles, boots & works just fine on my UP/SMP boxes.

Changes since -D2:

 - make rq->bitmap big-endian safe. (Anton Blanchard)

 - documented and cleaned up the load estimator bits, no functional
   changes apart from small speedups.

 - do init_idle() before starting up the init thread, this removes a race
   where we'd run the init thread on CPU#0 before init_idle() has been
   called.
