[GIT PULL] io_uring fixes for 5.12-rc5

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

- Use thread info versions of flag testing, as discussed last week.

- The series enabling PF_IO_WORKER to just take signals, instead of
  needing to special case that they do not in a bunch of places. Ends up
  being pretty trivial to do, and then we can revert all the special
  casing we're currently doing.

- Kill dead pointer assignment

- Fix hashed part of async work queue trace

- Fix sign extension issue for IORING_OP_PROVIDE_BUFFERS

- Fix a link completion ordering regression in this merge window

- Cancelation fixes

Please pull!
