[GIT PULL] io_uring updates for 5.9-rc1

[Jens Axboe]

Hi Linus,

A mix of fixes and a few stragglers. In detail:

- Revert the bogus __read_mostly that we discussed for the initial pull
  request.

- Fix a merge window regression with fixed file registration error path
  handling.

- Fix io-wq numa node affinities.

- Series abstracting out an io_identity struct, making it both easier to
  see what the personality items are, and also easier to to adopt more.
  Use this to cover audit logging.

- Fix for read-ahead disabled block condition in async buffered reads,
  and using single page read-ahead to unify what
  generic_file_buffer_read() path is used.

- Series for REQ_F_COMP_LOCKED fix and removal of it (Pavel)

- Poll fix (Pavel)

Please pull!
