Subject: [PATCH 20/23] mm: percpu: remove unnecessary unlikely()
Date: Fri, 31 Aug 2018 01:34:26 +0300	[thread overview]
Message-ID: <20180830223429.30051-21-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.
