    Right, and that sounds like a bug. A the last dput() of a non-hashed
    dentry should make the dentry go away, and we _shouldn't_ have any inode
    with a double count.

    I wonder if maybe vfat (or even the VFS layer) has a dentry count leak
    somewhere, so that the "last" dput() doesn't actually see a d_count of
    zero because something else forgot to decrement it..
