    Seems the BPAM and QSAM are provided by dfsms. cp doesn't use those. At least cp doesn't call those directly.
    cp only use the APIs provide by LE and binder so far.

    The "Alloc Free" and "Open Close" should be pair. I don't quite understand the proposal.
    Could you provide more information what need be enhanced?
    Thanks
