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. http://marc.info/?l=linux-ext4&m=129324612305011&w=4 In addition, the 6th to the last is bugfix or cleanup patch. This patch set is for e2fsprogs git tree.
