A tiny SCHED_FIFO microoptimisation and comments changes make up the
staircase7.9 patch. I doubt anyone will notice any difference, but this
shows the relative stability/maturity of the scheduler now. Patches for
vanilla, 2.6.7-bk20 and 2.6.7-mm6 are available. The sched batch (idle
scheduling) and sched iso (soft real time scheduling) policies are also
available, stable and ready for prime time testing.
The sched batch and sched iso policies have been updated slightly. The
sched batch implementation should be safe for disk intensive loads while
still minimising it's cpu usage as much as possible.
I've resynced with 2.6.7-bk20 as the bk19 introduced the security fixes
so if you feel you need the security updates you should move to this
There was a small cfq bug Jens has just addressed and I've added the
incremental fix to that in the ck-dev, mm6 and bk20 snapshots. If you
use cfq (ck does by default) it is probably worth applying this fix.
