[GIT PULL UPDATED] workqueue changes for v4.5-rc1

Show all headers | View raw

Hello, Linus.  I messed up the request-pull part of the previous
message.  Here's the correct one.

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.
