Hi Linus,

Quieter week this time, which was both expected and desired. About half
of the below is fixes for this release, the other half are just fixes in
general. In detail:

- Fix the freezing of IO threads, by making the freezer not send them
  fake signals. Make them freezable by default.

- Like we did for personalities, move the buffer IDR to xarray. Kills
  some code and avoids a use-after-free on teardown.

- SQPOLL cleanups and fixes (Pavel)

- Fix linked timeout race (Pavel)

- Fix potential completion post use-after-free (Pavel)

- Cleanup and move internal structures outside of general kernel view
  (Stefan)

- Use MSG_SIGNAL for send/recv from io_uring (Stefan)

Please pull!
