[GIT PULL] io_uring fixes for 5.11-rc6

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

We got the cancelation story sorted now, so for all intents and
purposes, this should be it for 5.11 outside of any potential little
fixes that may come in. This pull request contains:

- task_work task state fixes (Hao, Pavel)

- Cancelation fixes (me, Pavel)

- Fix for an inflight req patch in this release (Pavel)

- Fix for a lock deadlock issue (Pavel)

Please pull!
