    ext4: Fix possible corruption when moving a directory

    When we are renaming a directory to a different directory, we need to
    update ‘..’ entry in the moved directory. However nothing prevents moved
    directory from being modified and even converted from the inline format
    to the normal format. When such race happens the rename code gets
    confused and we crash. Fix the problem by locking the moved directory.
