    Unfortunately most of the remaining BKL uses seem to be very subtle.
    Removing lock_kernel() correctly requires a deep understanding of the
    global locking semantics and may be very invasive. In the end it's
    also hard to be sure bugs haven't been introduced.

    Fixing up a filesystem's write locking doesn't sound like a very good
    newbie project to me.
