    You've enabled CONFIG_BASE_SMALL and so the major_names[] hashtable has
    just one element. device-mapper uses dynamic major allocation, the range
    of which is limited to the size of the top-level major_names[] array. You
    ran out of slots and register_blkdev() failed.

    So for now I guess we must drop base-small-shrink-major_names-hash.patch.

    Al, that code looks rather crappy. Shouldn't we be using an idr tree or

    Also, we can never generate a major number of zero if the caller passed in
    major=0. How come?
