[PATCH 1/5] netfilter: nf_conntrack: silence warning on falling back to vmalloc()

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2015-08-10 17:54:17
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

Since 88eab472ec21 ("netfilter: conntrack: adjust nf_conntrack_buckets default
value"), the hashtable can easily hit this warning. We got reports from users
that are getting this message in a quite spamming fashion, so better silence
this.
