Subject: [PATCH 2/8] tools/xenalyze: Avoid redundant check
Date: Thu, 25 Feb 2016 14:48:57 +0000	[thread overview]
Message-ID: <1456411743-17741-3-git-send-email-george.dunlap@eu.citrix.com> (raw)
In-Reply-To: <1456411743-17741-1-git-send-email-george.dunlap@eu.citrix.com>

Coverity notices that if !head is true, that !N can never be true.

Don't bother checking N, since we know it has to be at least one.

CID 1354243
