[Impact]
Unprivileged users could use io_uring to crash the system or potentially
privilege escalation.

[Backport]
io_uring was split into multiple files. Backported involved mostly applying
the same changes to the single io_ring.c file.

[Potential regression]
io_uring users could regress.

Pavel Begunkov (2):
  io_uring: fix tw losing poll events
  io_uring: make poll refs more robust
