Subject: [Xen-devel] [PATCH v3 04/11] xen/events: Remove unlikely() from WARN() condition
Date: Thu, 29 Aug 2019 19:50:18 +0300	[thread overview]
Message-ID: <20190829165025.15750-4-efremov@linux.com> (raw)
In-Reply-To: <20190829165025.15750-1-efremov@linux.com>

"unlikely(WARN(x))" is excessive. WARN() already uses unlikely()
internally.
