====================
pull-request: bpf 2020-11-28
1) Do not reference the skb for xsk's generic TX side since when looped
back into RX it might crash in generic XDP, from Björn Töpel.
2) Fix umem cleanup on a partially set up xsk socket when being destroyed,
from Magnus Karlsson.
3) Fix an incorrect netdev reference count when failing xsk_bind() operation,
from Marek Majtyka.
4) Fix bpftool to set an error code on failed calloc() in build_btf_type_table(),
from Zhen Lei.
