This series enables handling of fragged skbs in virtio and vhost parts. Newly logic won't be triggered, because SO_ZEROCOPY options is still impossible to enable at this moment (next bunch of patches from big set above will enable it). I've included changelog to some patches anyway, because there were some comments during review of last big patchset from the link above. Head for this patchset is: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=b38460bc463c54e0c15ff3b37e81f7e2059bb9bb Link to v1: https://lore.kernel.org/netdev/20230717210051.856388-1-AVKrasnov@sberdevices.ru/ Link to v2: https://lore.kernel.org/netdev/20230718180237.3248179-1-AVKrasnov@sberdevices.ru/ Link to v3: https://lore.kernel.org/netdev/20230720214245.457298-1-AVKrasnov@sberdevices.ru/ Link to v4: https://lore.kernel.org/netdev/20230727222627.1895355-1-AVKrasnov@sberdevices.ru/ Link to v5: https://lore.kernel.org/netdev/20230730085905.3420811-1-AVKrasnov@sberdevices.ru/ Link to v6: https://lore.kernel.org/netdev/20230814212720.3679058-1-AVKrasnov@sberdevices.ru/ Changelog: v3 -> v4: * Patchset rebased and tested on new HEAD of net-next (see hash above). v4 -> v5: * See per-patch changelog after ---. v5 -> v6: * Patchset rebased and tested on new HEAD of net-next (see hash above). * See per-patch changelog after ---. v6 -> v7: * Patchset rebased and tested on new HEAD of net-next (see hash above). * See per-patch changelog after ---.
