Patches against ext3 have been posted by Jan Kara and have been sucked
into the mm tree.  I don't know if Andrew is planning on waiting until
the next merge window, or is planning on pushing it sooner given that
it is a regression.  (These supercede the ones currently posted by
Eric in the BZ entry.)

Similar patches have been posted against ext4, and I will be handling
them in the ext4 tree.
