[GIT PULL] io_uring fixes for 6.3-rc2

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A few small fixes that should go into the 6.3 release:

- Stop setting PF_NO_SETAFFINITY on io-wq workers. This has been
  reported in the past as it confuses some applications, as some of
  their threads will fail with -1/EINVAL if attempted affinitized. Most
  recent report was on cpusets, where enabling that with io-wq workers
  active will fail. Just deal with the mask changing by checking when a
  worker times out, and then exit if we have no work pending.

- Fix an issue with passthrough support where we don't properly check if
  the file type has pollable uring_cmd support.

- Fix a reported W=1 warning on a variable being set and unused. Add a
  special helper for iterating these lists that doesn't save the
  previous list element, if that iterator never ends up using it.

Please pull!
