[GIT PULL] workqueue for v2.6.35-rc1

[GIT PULL] workqueue for v2.6.35-rc1

[Tejun Heo]

Hello, Linus.

Please pull from the following branch to receive wq changes for
v2.6.35-rc1.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq.git for-linus

Bulk of cmwq still waiting for scheduler hooks to be resolved, there
are only two commits for v2.6.35-rc1.

One adds comment to flush_scheduled_work() mostly warning about the
possibility of deadlock.  The other makes cancel_work_sync() clear
work->data which speeds up further cancel/flush requests on it and
also makes it safe to call cancel/flush on already canceled works even
if the previous workqueue is destroyed.

Thanks.
