    Hi Tejun

    I've inspected all scsi touching patches and refrained from comments
    on the simple rename bunch. They all look very good accept that one
    place. (which will effect 2 patches)

    There are few more places that can use blk_end_request_all() after
    these changes.

    (The same internet outage on this reply)

    Thanks
    Boaz
