This is 'just plain stupid'.
The 'bv_' prefix of the members of 'struct bvec' is there so that 'grep'
(etc) can be used to find the uses of the members.
In a 'struct skb_frag_struct' a sensible prefix might be 'sf_'.
OTOH it might be sensible to use (or embed) a 'struct bvec'
instead of 'skb_frag_struct'.
