Hi Linus,

We still have a pending fix for a cancelation issue, but it's still
being investigated and the plan is for that to hit 5.11-rc5. Changes in
this pull request:

- Dead mm handling fix (Pavel)

- SQPOLL setup error handling (Pavel)

- Flush timeout sequence fix (Marcelo)

- Missing finish_wait() for one exit case

Please pull!
