The attached patch can fix this problem.

I didn't find these failure on my box.
The attached patch opens the verbose mode of e4defrag to get more information later, it is
useful to find the problem of online defrag.
So, Could you test it again and send the output info to me?

The attached patch can fix this problem.

This patch can fix the following problem:
-- delete the code of setting the test_fs flag
-- open the verbose mode of e4defrag, it is useful to find the problem of online defrag
-- fix some bug of the Makefile
-- throw the utilities version info away
