Pablo Neira Ayuso says:
====================
The following patchset contains Netfilter fixes for net:
1) Fix deadlock in nfnetlink due to missing mutex release in error path,
from Ziyang Xuan.
2) Clean up pending autoload module list from nf_tables_exit_net() path,
from Shigeru Yoshida.
3) Fixes for the netfilter's reverse path selftest, from Phil Sutter.
All of these bugs have been around for several releases.
