Virtio net supports the case where the skb linear space is empty, so add priv_flags.

Also, the series you sent is showed up incorrectly on lore.kernel.org and patchwork.kernel.org. Seems like you used different To and Cc for its parts. Please use scripts/get_maintainer.pl to the whole series: scripts/get_maintainer.pl ../patch-build-skb-by-page/* And use one list of addresses for every message, so they wouldn't lost. Al
