Only include SCSI initiator header files in target code that needs these header files, namely the SCSI pass-through code and the tcm_loop driver. Change SCSI_SENSE_BUFFERSIZE into TRANSPORT_SENSE_BUFFER in target code because the former is intended for initiator code and the latter for target code. With this patch the only initiator include directives in target code that remain are as follows: $ git grep -nHE 'include .scsi/(scsi.h|scsi_host.h|scsi_device.h|scsi_cmnd.h)' drivers/target drivers/infiniband/ulp/{isert,srpt} drivers/usb/gadget/legacy/tcm_*.[ch] drivers/{vhost,xen} include/{target,trace/events/target.h} drivers/target/loopback/tcm_loop.c:29:#include <scsi/scsi.h> drivers/target/loopback/tcm_loop.c:31:#include <scsi/scsi_host.h> drivers/target/loopback/tcm_loop.c:32:#include <scsi/scsi_device.h> drivers/target/loopback/tcm_loop.c:33:#include <scsi/scsi_cmnd.h> drivers/target/target_core_pscsi.c:39:#include <scsi/scsi_device.h> drivers/target/target_core_pscsi.c:40:#include <scsi/scsi_host.h> drivers/xen/xen-scsiback.c:52:#include <scsi/scsi_host.h> /* SG_ALL */ Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
