| |
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.
