Subject: __nf_register_net_hook jump label splat
Date: Sun, 30 Sep 2018 01:04:09 +0200 [thread overview]
Message-ID: <20180929230409.GA27207@zn.tnic> (raw)
Hi people,
this is something new I'm triggering with rc5 + tip/master while rc4 +
tip/master is fine. Any ideas?
If I had to guess, it looks like this thing:
#ifdef HAVE_JUMP_LABEL
static_key_slow_inc(&nf_hooks_needed[pf][reg->hooknum]);
#endif
