Hello,

this patchset contains second and third parts of another big patchset
for MSG_ZEROCOPY flag support:
https://lore.kernel.org/netdev/20230701063947.3422088-1-AVKrasnov@xxxxxxxxxxxxxx/

During review of this series, Stefano Garzarella <sgarzare@xxxxxxxxxx>
suggested to split it for three parts to simplify review and merging:

1) virtio and vhost updates (for fragged skbs) (merged to net-next, see
link below)
2) AF_VSOCK updates (allows to enable MSG_ZEROCOPY mode and read
tx completions) and update for Documentation/. <-- this patchset
3) Updates for tests and utils. <-- this patchset

Part 1) was merged:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=71b263e79370348349553ecdf46f4a69eb436dc7

I think I fully reviewed the series ;-)

Tests are all passing here, including the new ones. I also added
vsock_perf and vsock_uring_test to my test suite!

So for vsock point of view everything looks fine.

Let's see if there is anything about net (MSG_ZEROCOPY flags, etc.)

Thanks,
Stefano
