Sorry, I should have been more explicit.   You need to do

"e2fsck -f -E fragcheck", and you will get a *heck* of a lot more than
a single line.  :-)

Really?  Hmm, I wouldn't have expected that.  So now I'd really love
to see the fragcheck results (both with and without the patch), and/or
the results of debugfs stat'ing all three files, both with and without
the patch.
