Cover letter [PATCH 0/4] address some hangs
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()?
