====================
pull-request: bpf 2018-07-07
The following pull-request contains BPF updates for your *net* tree.
Plenty of fixes for different components:
1) A set of critical fixes for sockmap and sockhash, from John Fastabend.
2) fixes for several race conditions in af_xdp, from Magnus Karlsson.
3) hash map refcnt fix, from Mauricio Vasquez.
4) samples/bpf fixes, from Taeung Song.
5) ifup+mtu check for xdp_redirect, from Toshiaki Makita.
