Merge tag 'for-5.20/io_uring-zerocopy-send-2022-07-29' of git://git.kernel.dk/linux-block
Pull io_uring zerocopy support from Jens Axboe:
"This adds support for efficient support for zerocopy sends through
io_uring. Both ipv4 and ipv6 is supported, as well as both TCP and
UDP.
The core network changes to support this is in a stable branch from
Jakub that both io_uring and net-next has pulled in, and the io_uring
changes are layered on top of that.
All of the work has been done by Pavel"
