Subject: [PATCH 04/46] Staging: hv: storvsc: Rename get_stor_device()
Date: Sat, 27 Aug 2011 11:31:03 -0700	[thread overview]
Message-ID: <1314469905-7058-4-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1314469905-7058-1-git-send-email-kys@microsoft.com>

In preparation for cleaning up how we manage reference counts on the stor
device, clearly distinguish why we are attempting to acquire a reference.
