Hi Linus,

Mostly fixes for regressions in this cycle, but also a few fixes that
predate this release. The odd one out is a tweak to the direct files
added in this release, where attempting to reuse a slot is allowed
instead of needing an explicit removal of that slot first. It's a
considerable improvement in usability to that API, hence I'm sending it
for -rc2.

- io-wq race fix and cleanup (Hao)

- loop_rw_iter() type fix

- SQPOLL max worker race fix

- Allow poll arm for O_NONBLOCK files, fixing a case where it's
  impossible to properly use io_uring if you cannot modify the file
  flags

- Allow direct open to simply reuse a slot, instead of needing it
  explicitly removed first (Pavel)

- Fix a case where we missed signal mask restoring in cqring_wait, if we
  hit -EFAULT (Xiaoguang)

Please pull!
