[PATCHSET 0/4] io_uring and task_work interactions

[Jens Axboe <axboe@kernel.dk>]

There's a case for io_uring where we want to run the task_work on ring
exit, but we can't easily do that as we don't know if the task_works has
work, or if exit work has already been queued.

Here's two prep patches that adds a task_work_pending() helper, and
makes task_work_run() check it. Then we can remove these checks from
the caller, and we can have io_uring check if we need to run work if
it needs to on ring exit.
