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!
