Subject: [PATCH v2 0/2] Minor SQPOLL thread fix and improvement
Date: Wed, 23 Jun 2021 11:50:04 -0700 [thread overview]
Message-ID: <cover.1624473200.git.olivier@trillion01.com> (raw)
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
