-Subject: kernel/io_uring: cancel io_uring before task works
-
-From: Pavel Begunkov <asml.silence@gmail.com>
-
-commit b1b6b5a30dce872f500dc43f067cba8e7f86fc7d upstream.
-
-For cancelling io_uring requests it needs either to be able to run
-currently enqueued task_works or having it shut down by that moment.
-Otherwise io_uring_cancel_files() may be waiting for requests that won't
-ever complete.
-
-Go with the first way and do cancellations before setting PF_EXITING and
-so before putting the task_work infrastructure into a transition state
-where task_work_run() would better not be called.
