Subject: [PATCH 3.10 14/43] mptfusion: enable no_write_same for vmware scsi disks
Date: Tue, 28 Oct 2014 11:36:12 +0800	[thread overview]
Message-ID: <20141028033524.013560111@linuxfoundation.org> (raw)
In-Reply-To: <20141028033523.407092670@linuxfoundation.org>

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chris J Arges <chris.j.arges@canonical.com>

commit 4089b71cc820a426d601283c92fcd4ffeb5139c2 upstream.

When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used
data can be improperly zeroed out using the mptfusion driver. This patch
disables write_same for this driver and the vmware subsystem_vendor which
ensures that manual zeroing out is used instead.
