[PATCH v3 0/3] async punting improvements for io_uring

[Pavel Begunkov <asml.silence@gmail.com>]

*on top of for-5.6*

This cleans up io-wq punting paths, doing small fixes and removing
unnecessary logic from different submission paths.

v2:
- remove pid-related comment, as it's fixed separately
- make ("add missing io_req_cancelled()") first
  in the series, so it may be picked for 5.6

v3:
- rebase + drop a patch definitely colliding with poll work

Pavel Begunkov (3):
  io_uring: don't call work.func from sync ctx
  io_uring: don't do full *prep_worker() from io-wq
  io_uring: remove req->in_async
