[PATCHSET 0/2] Add support for IORING_CQE_F_SOCK_FULL

[Jens Axboe <axboe@kernel.dk>]

Hi,

It can be useful for userspace to know if a send request had to go
through poll to complete, as that generally means that the socket was
out of space. On the send side, this is pretty trivial to support - we
just need to check if the request needed to go through poll to complete.

This reuses the IORING_CQE_F_SOCK_NONEMPTY flag value, which is only
valid for recv operations. As IORING_CQE_F_SOCK_FULL only applies on
sends, there's no need for separate values for this flag.

Based on an earlier patchset, which utilized REQ_F_POLL_ARMED instead
and handled patch 1 a bit differently.
