[PATCH 0/2] ipset patches for nf

[Jozsef Kadlecsik <kadlec@netfilter.org>]

Hi Pablo,

Please consider to apply the next two patches to the nf tree. The first one
is larger than usual, but the issue could not be solved simpler. Also, it's
a resend of the patch I submitted a few days ago, with a one line fix on
top of that: the size of the comment extensions was not taken into account
at reporting the full size of the set.

- Fix "INFO: rcu detected stall in hash_xxx" reports of syzbot
  by introducing region locking and using workqueue instead of timer based
  gc of timed out entries in hash types of sets in ipset.
- Fix the forceadd evaluation path - the bug was also uncovered by the syzbot.

Best regards,
Jozsef
