    ext4: let ext4_rename handle inline dir · 32f7f22c

    In case we rename a directory, ext4_rename has to read the dir block
    and change its dotdot's information.  The old ext4_rename encapsulated
    the dir_block read into itself.  So this patch adds a new function
    ext4_get_first_dir_block() which gets the dir buffer information so
    the ext4_rename can handle it properly.  As it will also change the
    parent inode number, we return the parent_de so that ext4_rename() can
    handle it more easily.
    
    ext4_find_entry is also changed so that the caller(rename) can tell
    whether the found entry is an inlined one or not and journaling the
    corresponding buffer head.
