Revision b90ddd568792bcb0054eaf0f61785c8f80c3bd1c authored by Willem de Bruijn on 20 December 2017, 22:37:50 UTC, committed by David S. Miller on 21 December 2017, 20:00:58 UTC
skb_copy_ubufs creates a private copy of frags[] to release its hold
on user frags, then calls uarg->callback to notify the owner.
Call uarg->callback even when no frags exist. This edge case can
happen when zerocopy_sg_from_iter finds enough room in skb_headlen
to copy all the data.
Fixes: 3ece782693c4 ("sock: skb_copy_ubufs support for compound pages")
