Subject: [PATCH 3/3] scsi: Use try_rc16 and try_vpd_pages quirks on Hyper-V virtual disks
Date: Fri, 10 Oct 2014 08:55:02 +0100	[thread overview]
Message-ID: <20141010075502.GD32028@sucs.org> (raw)
In-Reply-To: <20141010074901.GA32028@sucs.org>

Microsoft Hyper-V virtual disks currently only claim SPC-2 compliance causing
feature tests not to be run (even though those features are correctly announced
elsewhere). Make Hyper-V virtual disks quirk past READ CAPACITY(16) and VPD
page guards so appropriate tests are performed.

This only impacts Hyper-V's VHD/VHDX virtual disks and not passthrough devices.
