Subject: [iproute PATCH v2 5/7] ss: Skip useless check in parse_hostcond()
Date: Thu, 17 Aug 2017 19:09:29 +0200 [thread overview]
Message-ID: <20170817170931.24089-6-phil@nwl.cc> (raw)
In-Reply-To: <20170817170931.24089-1-phil@nwl.cc>
The passed 'addr' parameter is dereferenced by caller before and in
parse_hostcond() multiple times before this check, so assume it is
always true.
