Hi Linus,

io_uring fixes that should go into this release:

- Catch a case where io_sq_thread() didn't do proper mm acquire

- Ensure poll completions are reaped on shutdown

- Async cancelation and run fixes (Pavel)

- io-poll race fixes (Xiaoguang)

- Request cleanup race fix (Xiaoguang)

Please pull!
