[GIT PULL] workqueue fixes for v3.7-rc2

[Tejun Heo <tj@kernel.org>]

Hello, Linus.

This pull request contains one patch from Dan Magenheimer to fix
cancel_delayed_work() regression introduced by its reimplementation
using try_to_grab_pending().  The reimplementation made it incorrectly
return %true when the work item is idle.  There aren't too many
consumers of the return value but it broke at least ramster.

Please pull from the following branch to receive the fix.
