    block: move __dev from disk to part0 · 548b10eb
    Tejun Heo authored
    Move disk->__dev to part0->__dev.  This simplifies bdget_disk() and
    lookup_devt() and allows common sysfs attributes to be unified.
    part_to_disk() is updated to handle part0 -> disk.
    
    Updated to include a fix from Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>,
    he writes:
    
    "part0 is a "special" partition and doesn't need to have capacity set - this
    fixes regression caused by "block: move __dev from disk to part0" commit."
