Subject: [PATCH 07/23] seccomp: remove unnecessary unlikely()
Date: Fri, 31 Aug 2018 01:34:13 +0300 [thread overview]
Message-ID: <20180830223429.30051-8-igor.stoppa@huawei.com> (raw)
In-Reply-To: <20180830223429.30051-1-igor.stoppa@huawei.com>
WARN_ON() already contains an unlikely(), so it's not necessary to wrap it
into another.
