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 60cc1f7d0605598b47ee3c0c2b4b6fbd4da50a06 Arseniy Krasnov (4): vsock/virtio/vhost: read data from non-linear skb vsock/virtio: support to send non-linear skb vsock/virtio: non-linear skb handling for tap vsock/virtio: MSG_ZEROCOPY flag support drivers/vhost/vsock.c | 14 +- include/linux/virtio_vsock.h | 1 + net/vmw_vsock/virtio_transport.c | 40 ++- net/vmw_vsock/virtio_transport_common.c | 310 ++++++++++++++++++------ 4 files changed, 283 insertions(+), 82 deletions(-)
