Chris J Arges e6f0636b61 mptfusion: enable no_write_same for vmware scsi disks ... 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.
