Hi Linus,

Here's a set of fixes that should go into this release. A bit bigger
than usual at this point in time, mostly due to some good bug hunting
work by Pavel that resulted in 3 io_uring fixes from him and 2 from me.
Anyway, this pull request contains:

- Revert of the submit-and-wait optimization for io_uring, it can't
  always be done safely. It depends on commands always making progress
  on their own, which isn't necessarily the case outside of strict file
  IO. (me)

- Series of 2 patches from me and 3 from Pavel, fixing issues with
  shared data and sequencing for io_uring.

- Lastly, two timeout sequence fixes for io_uring (zhangyi)

- Two nbd patches fixing races (Josef)

- libahci regulator_get_optional() fix (Mark)

Please pull!
