From eb37f14658df23c51f172bddb0c45eecf408927c Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Mon, 29 Jul 2013 14:49:29 +1000 Subject: spapr-vscsi: add task management At the moment the guest kernel issues two types of task management requests to the hypervisor - task about and lun reset. This adds handling for these tasks. As spapr-vscsi starts calling scsi_req_cancel(), free_request callback was implemented. As virtio-vscsi, spapr-vscsi does not handle CLEAR_ACA either as CDB control byte does not seem to be used at all so NACA bit is not set to the guest so the guest has no good reason to call CLEAR_ACA task.
