Subject: [GIT PULL] io_uring fixes for 5.6-rc2

Hi Linus,

Here's a set of fixes for io_uring that should go into this release.
This pull request contains:

- Various fixes with cleanups from Pavel, fixing corner cases where
  we're not correctly dealing with iovec cleanup.

- Clarify that statx/openat/openat2 don't accept fixed files

- Buffered raw device write EOPTNOTSUPP fix

- Ensure async workers grab current->fs

- A few task exit fixes with pending requests that grab the file table

- send/recvmsg async load fix

- io-wq offline node setup fix

- CQ overflow flush in poll

Please pull!
