Subject: [PATCH 6/9] virtio-serial: Remove redundant check for 0-sized write request
Date: Fri, 19 Mar 2010 17:28:43 +0530 [thread overview]
Message-ID: <1268999926-29560-7-git-send-email-amit.shah@redhat.com> (raw)
In-Reply-To: <1268999926-29560-6-git-send-email-amit.shah@redhat.com>
The check for a 0-sized write request to a guest port is not necessary;
the while loop below won't be executed in this case and all will be
fine.
