Subject: [PATCH 12/28] Drivers: hv: Change the signature of vmbus_set_event()
Date: Sat, 1 Dec 2012 06:46:43 -0800 [thread overview]
Message-ID: <1354373219-31374-12-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1354373219-31374-1-git-send-email-kys@microsoft.com>
In preparation for supporting a per-connection signaling mechanism,
change the signature of vmbus_set_event(). This change is also
needed to implement other aspects of the signaling optimization.
