Move the DMA handle into the per-command private data instead of using the SCSI pointer from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

Set scsi_host_template.cmd_size instead of using the SCSI pointer for storing driver-private data. Change the type of the argument of uas_add_work() from struct uas_cmd_info * into struct scsi_cmnd * because it is easier to convert a SCSI command pointer into a uas_cmd_info pointer than the other way around.

Instead of using the SCp.ptr field to track whether or not a command is in flight, use the sp->type field to track this information. sp->type must be set for proper operation of the qla2xxx driver. See e.g. the switch (sp->type) statement in qla2x00_ct_entry(). This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

Instead of storing the iSCSI task pointer and the session age in the SCSI pointer, use command-private variables. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd. The list of iSCSI drivers has been obtained as follows: $ git grep -lw iscsi_host_alloc drivers/infiniband/ulp/iser/iscsi_iser.c drivers/scsi/be2iscsi/be_main.c drivers/scsi/bnx2i/bnx2i_iscsi.c drivers/scsi/cxgbi/libcxgbi.c drivers/scsi/iscsi_tcp.c drivers/scsi/libiscsi.c drivers/scsi/qedi/qedi_main.c drivers/scsi/qla4xxx/ql4_os.c include/scsi/libiscsi.h Note: it is not clear to me how the qla4xxx driver can work without this patch since it uses the scsi_cmnd::SCp.ptr member for two different purposes: - The qla4xxx driver uses this member to store a struct srb pointer. - libiscsi uses this member to store a struct iscsi_task pointer.
