feat: add support for IORING_CQE_F_SOCK_NONEMPTY flag during socket recv #192

Closed romange closed 9 months ago

romange commented 9 months ago

This applies only for recent version of iouring. In case the receive buffer was empty (i.e. we have not got IORING_CQE_F_SOCK_NONEMPTY flag) we can save the internal call to recv inside kernel by flagging the receive operation with IORING_RECVSEND_POLL_FIRST.
