Merge branch 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue fixes from Tejun Heo: "Fixes for two bugs in workqueue. One is exiting with internal mutex held in a failure path of wq_update_unbound_numa(). The other is a subtle and unlikely use-after-possible-last-put in the rescuer logic. Both have been around for quite some time now and are unlikely to have triggered noticeably often. All patches are marked for -stable backport" * 'for-3.15-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: fix a possible race condition between rescuer and pwq-release workqueue: make rescuer_thread() empty wq->maydays list before exiting workqueue: fix bugs in wq_update_unbound_numa() failure path
