Subject[GIT PULL] io_uring fixes for 5.5-rc7
Date
Hi Linus,

A set of fixes that should go into this release. This pull request
contains:

- Ensure ->result is always set when IO is retried (Bijan)

- In conjunction with the above, fix a regression in polled IO issue
when retried (me/Bijan)

- Don't setup async context for read/write fixed, otherwise we may
wrongly map the iovec on retry (me)

- Cancel io-wq work if we fail getting mm reference (me)

- Ensure dependent work is always initialized correctly (me)

- Only allow original task to submit IO, don't allow it from a passed
ring fd (me)

Please pull!
