Hi, I had a re-think on the flags2 addition [1] that was posted earlier today, and I don't really like the fact that flags2 then can't work with ioprio for read/write etc. We might also want to extend the ioprio field for other types of IO in the future. So rather than do that, do a simpler approach and just add an io_uring specific flag set for send/recv and friends. This then allow setting IORING_RECVSEND_POLL_FIRST in sqe->addr2 for those, and if set, io_uring will arm poll first rather than attempt a send/recv operation.
