Merge tag 'io_uring-5.15-2021-10-01' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "Two fixes in here:

   - The signal issue that was discussed start of this week (me).

   - Kill dead fasync support in io_uring. Looks like it was broken
     since io_uring was initially merged, and given that nobody has ever
     complained about it, let's just kill it (Pavel)"
