Subject: [PATCH -tip 0/3] sched: some fixes for vruntime calculation related to cgroup movement(v2)
Date: Thu, 15 Dec 2011 14:35:06 +0900 [thread overview]
Message-ID: <20111215143506.335e443e.nishimura@mxp.nes.nec.co.jp> (raw)

Hi, all.
This is an updated version based on comments and rebased onto the -tip tree.
These patches fix problems I could see in 3.2-rc2 when testing frequent cgroup movement
under very high load. Without these patches, some processes were not scheduled
(although they were queued into rq)for a very long time(minutes or hours!),
because vruntime of these processes were far bigger than min_vruntime.
Daisuke Nishimura (3):
sched: fix cgroup movement of newly created process
sched: fix cgroup movement of forking process
sched: fix cgroup movement of waking process
