Cover letter [PATCH v3 0/3] Inline sqe_submit
The idea is to not pass struct sqe_submit as a separate entity, but always use req->submit instead, so there will be less stuff to care about.
Also, I've got steady +1% throughput improvement for nop tests. Though, it's highly system-dependent, and I wouldn't count on it.
