Subject: [PATCH 00/11] e4defrag: fragmentation score rework and cleanups

Hi,

This patch set adds the new function get_fragment_score() to libe2p, that
calculates the fragmentation score. Fragmentation score shows how badly
fragmented the file might be. filefrag uses it to make a user understand
the status of the file fragmentation easily. And e4defrag also uses it
to determine smarter whether to call EXT4_IOC_MOVE_EXT ioctl. This improvement
is based on the following Ted's idea.

In addition, the 6th to the last is bugfix or cleanup patch.

This patch set is for e2fsprogs git tree. (commit:5af9eeaa7d)
