[Devel] [KERNEL COMMIT]: diff-fairsched-loadbal-20051201

[Kirill Korotaev]

Committed in 022stab052

Patch from Kirill (dev@):
This patch removes warning on load balance.
Balancing is racy, and it is not fatal anyhow if
busiest rq is the current one. printk() under
rq->lock can be the much more fatal thing here...
Bug #55290
