| 2023-08-16 | io_uring/sqpoll: fix io-wq affinity when IORING_SETUP_SQPOLL is used | Jens Axboe | 1 | -0/+1 | |
| If we setup the ring with SQPOLL, then that polling thread has its own io-wq setup. This means that if the application uses IORING_REGISTER_IOWQ_AFF to set the io-wq affinity, we should not be setting it for the invoking task, but rather the sqpoll task. Add an sqpoll helper that parks the thread and updates the affinity, and use that one if we're using SQPOLL.

| Change the return type to void since it always return 0, and no need to do the checking in syscall io_uring_enter. Signed-off-by: Quanfa Fu <quanfafu@gmail.com> Link: https://lore.kernel.org/r/20230115071519.554282-1-quanfafu@gmail.com Signed-off-by: Jens Axboe <axboe@kernel.dk> | |||||
