As what I have said in [PATCH 0/4], this serial patches are apply to
Martin's 4.16/scsi-queue only. Now scsi/for-next and next-20171213 are
synchronized to Martin's 4.16/scsi-queue, so these patches can apply to
them. But v4.15-rc3 has to do some patches like 4.16/scsi-queue done
before, or this patch can not apply.
