Description Vivek Goyal 2011-05-25 20:56:13 UTC

Description of problem:

There are few race condition fixes and cleanups which went upstream in blkio controller related code (blk-cgroup, blk-throttle, cfq-iosched). Pick some of
the changes and pull in 6.2.

This also helps backporting the lockless IO throttling patches in otherwise
patches don't apply as their are dependencies.
