You may need a slightly modified userspace utility from what Akira-san
posted, which you can get here:

http://repo.or.cz/w/ext4-patch-queue.git?a=blob_plain;f=online-defrag-cmd;h=7d42ad5cdb6813d262201d6806531f189d3d1f57;hb=35e9fa546ac349cb9a7c4ee9e45ff9747edd9335

This reflects a change that I made in the structure passed in the new
EXT4_IOC_MOVE_EXT ioctl.

Note that I have not done a lot of stress testing of the defrag
functionality, so please be careful using it on production systems.
Please make sure you backup your files before trying to use it.
