Subject: [PATCH 04/49] Staging: hv: storvsc: Fix a bug in the storvsc_remove() function
Date: Mon, 6 Jun 2011 15:49:28 -0700 [thread overview]
Message-ID: <1307400613-13234-4-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1307400613-13234-1-git-send-email-kys@microsoft.com>
When the storvs driver unloads, we need to accomodate disk cache flushes.
Re-order the code to permit this.
