Jens Axboe 47de1a773e io_uring: disable io-wq execution of multishot NOWAIT requests ... Commit bee1d5becd upstream. Do the same check for direct io-wq execution for multishot requests that commit 2a975d426c did for the inline execution, and disable multishot mode (and revert to single shot) if the file type doesn't support NOWAIT, and isn't opened in O_NONBLOCK mode. For multishot to work properly, it's a requirement that nonblocking read attempts can be done.
