3.16.46-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Max Lohrmann <redacted>

commit 13603685c1f12c67a7a2427f00b63f39a2b6f7c9 upstream.

As reported by Max, the Windows 2008 R2 chkdsk utility expects
VERIFY_16 to be supported, and does not handle the returned
CHECK_CONDITION properly, resulting in an infinite loop.

The kernel will log huge amounts of this error:

kernel: TARGET_CORE[iSCSI]: Unsupported SCSI Opcode 0x8f, sending
CHECK_CONDITION.
