Subject[13/90] ext4: Allow rename to create more than EXT4_LINK_MAX subdirectories
2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
(cherry picked from commit 2c94eb86c66e1eaaa1e7d8a2120f4fad5e7e7736)
Use EXT4_DIR_LINK_MAX so that rename() can move a directory into new
parent directory without running into the EXT4_LINK_MAX limit.
