Subject: [patch -master] netfilter: xt_CT: checking for IS_ERR() instead of NULL
Date: Tue, 28 Jul 2015 01:42:28 +0300	[thread overview]
Message-ID: <20150727224228.GA10367@mwanda> (raw)

We recently changed this from nf_conntrack_alloc() to nf_ct_tmpl_alloc()
so the error handling needs to changed to check for NULL instead of
IS_ERR().

Fixes: 0838aa7fcfcd ('netfilter: fix netns dependencies with conntrack templates')
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
