io_uring: cap SQ submit size for SQPOLL with multiple rings In the spirit of fairness, cap the max number of SQ entries we'll submit for SQPOLL if we have multiple rings. If we don't do that, we could be submitting tons of entries for one ring, while others are waiting to get service. The value of 8 is somewhat arbitrarily chosen as something that allows a fair bit of batching, without using an excessive time per ring. Signed-off-by: Jens Axboe <axboe@kernel.dk>
