*lost the cover-letter, but here we go*
The main idea is to optimise code like the following by directly copying sqe flags:
if (sqe_flags & IOSQE_IO_HARDLINK) req->flags |= REQ_F_HARDLINK;
The first patch is a minor cleanup, and the second one do the trick. No functional changes.
The other thing to consider is whether to use such flags as REQ_F_LINK = IOSQE_IO_LINK, or directly use IOSQE_IO_LINK instead.
