It's to guarantee forward progress for workqueues which process work items which may be used to reclaim memory. It reserves a rescue worker thread to be used under memory pressure. I finished workqueue documentation a few days ago and sent pull request to Linus. http://git.kernel.org/?p=linux/kernel/git/tj/wq.git;a=blob;f=Documentation/workqueue.txt;h=e4498a2872c37a0b3b156ddc7ad7135d030d224d;hb=c54fce6eff197d9c57c97afbf6c9722ce434fc8f So, for pm_wq, there's no reason to use WQ_RESUER. alloc_workqueue("pm", WQ_FREEZEABLE, 0) should do it. Thanks for doing it. -- tejun _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
