[PATCH 0/3] [RFC] conntrack event caching changes

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi Patrick,

This is another round of the event caching rework. I'm not including
patch from 1/5 to 3/5 that I previously sent that are required by these
patches but that are not relevant for the RFC I think.

Basically, this rework contains:

a) The replacement for the use of the notify chain by a single function
pointer.
b) The replacement of the per-cpu event cache by a per-conntrack event
cache.
c) The addition of optional reliable conntrack event delivery containing
the recent comments during one of our discussions.

Thanks!
