Merge tag 'io_uring-6.1-2022-10-22' of git://git.kernel.dk/linux
Pull io_uring follow-up from Jens Axboe:
"Currently the zero-copy has automatic fallback to normal transmit, and
it was decided that it'd be cleaner to return an error instead if the
socket type doesn't support it.
Zero-copy does work with UDP and TCP, it's more of a future proofing
kind of thing (eg for samba)"
