Message-ID: <1441124673-3438470-2-git-send-email-tom@herbertland.com>

Subject: [PATCH net-next 01/11] flow_dissector: Move skb related functions to skbuff.h
Move the flow dissector functions that are specific to skbuffs into
skbuff.h out of flow_dissector.h. This makes flow_dissector.h have
no dependencies on skbuff.h.
