Subject: [PATCH v2 0/2] Minor SQPOLL thread fix and improvement

I have been investigated a deadlock situation in my io_uring usage where
the SQPOLL thread was going to sleep and my user threads were waiting
inside io_uring_enter() for completions.

https://github.com/axboe/liburing/issues/367

This patch serie is the result of my investigation.

Olivier Langlois (2):
  io_uring: Fix race condition when sqp thread goes to sleep
  io_uring: Create define to modify a SQPOLL parameter
