    reiserfs: locking, handle nested locks properly · 278f6679
    Jeff Mahoney authored
    The reiserfs write lock replaced the BKL and uses similar semantics.
    
    Frederic's locking code makes a distinction between when the lock is nested
    and when it's being acquired/released, but I don't think that's the right
    distinction to make.
    
    The right distinction is between the lock being released at end-of-use and
    the lock being released for a schedule. The unlock should return the depth
    and the lock should restore it, rather than the other way around as it is now.
    
    This patch implements that and adds a number of places where the lock
    should be dropped.
