08:34	[PATCH] io_uring/sqpoll: make io_sq_thread_stop() idempotent IO_SQ_THREAD_SHOULD_STOP may already be set when io_sq_thread() exits on its own. The last ring still calls io_sq_thread_stop() from io_put_sq_data(), which tripped WARN_ON_ONCE(). Reproduced on 7.4-rc1 with IORING_SETUP_SQPOLL + close(ring_fd), which triggered WARNING at io_uring/sqpoll.c:88 before this patch. With this patch applied, the same repro no longer warns (also verified via QEMU initramfs repro).
