From f0ad462189cc898aa0ef8ced849533ee03392bcc Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Thu, 23 Jul 2015 13:06:10 +0200 Subject: [PATCH] netfilter: nf_conntrack: silence warning on falling back to vmalloc() 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.
