io_uring: use system_unbound_wq for ring exit work We currently use system_wq, which is unbounded in terms of number of workers. This means that if we're exiting tons of rings at the same time, then we'll briefly spawn tons of event kworkers just for a very short blocking time as the rings exit. Use system_unbound_wq instead, which has a sane cap on the concurrency level. Signed-off-by: Jens Axboe <axboe@kernel.dk>
