Subject: [PATCH 3/5] net/9p: Add a jump target in p9_client_walk()
Date: Tue, 15 Aug 2017 14:01:11 +0200	[thread overview]
Message-ID: <5b39be44-cbec-9838-77c6-00b99f5fe0a2@users.sourceforge.net> (raw)
In-Reply-To: <22a44d7c-cdb9-e206-4b2c-56e38cbf0de1@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 15 Aug 2017 10:07:22 +0200

Replace a variable assignment by a goto statement so that an extra check
will be avoided at the end of this function.
