Subject: [PATCH 0/4] address some hangs
Date: Wed, 30 Dec 2020 21:34:13 +0000	[thread overview]
Message-ID: <[email protected]> (raw)

1/4 and 2/4 are for hangs during files unregister.

The other two fix not running task works during cancellation.
Instead of patching task_work it moves io_uring_files_cancel()
before PF_EXITING, should be less intrusive. Was there a
particular reasong for doing that in exit_files()?

Pavel Begunkov (4):
  io_uring: add a helper for setting a ref node
  io_uring: fix io_sqe_files_unregister() hangs
  kernel/io_uring: cancel io_uring before task works
  io_uring: cancel requests enqueued as task_work's
