Subject: [PATCH 07/13] storvsc: set virt_boundary_mask in the scsi host template
Date: Wed, 5 Jun 2019 21:08:30 +0200 [thread overview]
Message-ID: <20190605190836.32354-8-hch@lst.de> (raw)
In-Reply-To: <20190605190836.32354-1-hch@lst.de>
This ensures all proper DMA layer handling is taken care of by the
SCSI midlayer.
