Subject: [PATCH 7/9] staging: hv: fix counting of available buffer slots when send fails
Date: Thu, 21 Jul 2011 10:14:55 -0700 [thread overview]
Message-ID: <1311268497-8671-8-git-send-email-haiyangz@microsoft.com> (raw)
In-Reply-To: <1311268497-8671-1-git-send-email-haiyangz@microsoft.com>
Because the number of available buffer slots doesn't decrease for failed
sends, we should not call netvsc_xmit_completion(), which increase the
count of available slots. In this failed case, just free the memory is
enough.
