Subject: [PATCH 16/23] lvm: device mapper: remove unnecessary unlikely()
Date:   Fri, 31 Aug 2018 01:34:22 +0300
Message-Id: <20180830223429.30051-17-igor.stoppa@huawei.com>
In-Reply-To: <20180830223429.30051-1-igor.stoppa@huawei.com>
References: <20180830223429.30051-1-igor.stoppa@huawei.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

WARN_ON() already contains an unlikely(), so it's not necessary to
wrap it into another.
