    The RQF_COPY_USER is set for bio where the passthrough request mapping
    helpers decided that bounce buffering is required.  It is then used to
    pad scatterlist for drivers that required it.  But given that
    non-passthrough requests are per definition aligned, and directly mapped
    pass-through request must be aligned it is not actually required at all.
