I'm actually not sure if __must_check helps us anything given that with this patch applied: johannes@redsun60:linux(zone-append-wip)$ git --no-pager grep -n \ scsi_setup_fs_cmnd drivers/scsi drivers/scsi/scsi_lib.c:1173: static blk_status_t scsi_setup_fs_cmnd(struct scsi_device *sdev, drivers/scsi/scsi_lib.c:1205: ret = scsi_setup_fs_cmnd(sdev, req); there's only one caller of scsi_setup_fs_cmnd(), in the same file, 32 lines below the implementation. I do agree about the Link or an eventual Cc: stable, but I think Martin or Jens can add this when applying the patch.
