[GIT PULL] io_uring fixes for 6.1-rc6

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A few fixes that should go into this release:

- A few poll related fixes. One fixing a race condition between poll
  cancelation and trigger, and one making the overflow handling a bit
  more robust (Lin, Pavel)

- Fix an fput() for error handling in the direct file table (Lin)

- Fix for a regression introduced in this cycle, where we don't always
  get TIF_NOTIFY_SIGNAL cleared appropriately (me)

Please pull!
