Subjectio_uring_enter() with opcode IORING_OP_RECV ignores MSG_WAITALL in msg_flags
Date
I get partial receives on TCP socket, even though I specify MSG_WAITALL 
with IORING_OP_RECV opcode. Looking at tcpdump in wireshark, I see
entire reassambled packet (+4k), so it is not a disconnect. The MTU is
smaller than 4k.

From
the mailing list history, looks like this was discussed before and it
seems the fix was supposed to be in. Can someone clarify the expected
behavior?

I do not think rsvmsg() has this issue.
