Pavel Begunkov 0def123f12 io_uring: break out of iowq iopoll on teardown ... [ upstream commit 45500dc4e0 ] io-wq will retry iopoll even when it failed with -EAGAIN. If that races with task exit, which sets TIF_NOTIFY_SIGNAL for all its workers, such workers might potentially infinitely spin retrying iopoll again and again and each time failing on some allocation / waiting / etc. Don't keep spinning if io-wq is dying.
