From d139b9bd0e52dda14fd13412e7096e68b56d0076 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 5 Nov 2009 13:33:12 -0600 Subject: [SCSI] scsi_lib_dma: fix bug with dma maps on nested scsi objects Some of our virtual SCSI hosts don't have a proper bus parent at the top, which can be a problem for doing DMA on them This patch makes the host device cache a pointer to the physical bus device and provides an extra API for setting it (the normal API picks it up from the parent). This patch also modifies the qla2xxx and lpfc vport logic to use the new DMA host setting API.
