io_uring: batch account ->req_issue and task struct references Identical to how we handle the ctx reference counts, increase by the batch we're expecting to submit, and handle any slow path residual, if any. The request alloc-and-issue path is very hot, and this makes a noticeable difference by avoiding an two atomic incs for each individual request. Signed-off-by: Jens Axboe <axboe@kernel.dk>
