Subject[GIT PULL] workqueue changes for v4.5-rc1
Hello, Linus.

workqueue changes for v4.5. One cleanup patch and three to improve
the debuggability. Workqueue now has a stall detector which dumps
workqueue state if any worker pool hasn't made forward progress over a
certain amount of time (30s by default) and also triggers a warning if
a workqueue which can be used in memory reclaim path tries to wait on
something which can't be. These should make workqueue hangs a lot
easier to debug.

Thanks.

The following changes since commit afd2ff9b7e1b367172f18ba7f693dfb62bdcb2dc:
