[PATCHSET,0/2] Accept tweaks

Hi,

Add support for a forced nonblock accept attempt, returning -EAGAIN
if nothing is there to accept rather than arm poll. This is similar to
similarly provided "-EAGAIN is final" for other opcodes.

Add support for doing polling first on accept. Again similar to support
we have for eg recv/recvmsg on relying on poll before initiating the
first accept request, avoiding expensive setup only to tear it down and
wait for a retry.
