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)"
