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. (commit:5af9eeaa7d)
Kazuya Mio (11):
libe2p: Add new function get_fragment_score()
filefrag: Output fragmentation score
e4defrag: Remove -c option which check the file fragments
e4defrag: Remove old fragmentation score calculation code
e4defrag: Use get_fragment_score() for decision of whether to defrag
e4defrag: Allow user who has read+write permission to defrag
e4defrag: Fix memory leak in file_defrag()
e4defrag: Use blk64_t instead of ext4_fsblk_t
e4defrag: Use EXT2_SUPER_MAGIC instead of EXT4_SUPER_MAGIC
e4defrag: Fix error messages more clearly
e4defrag: Remove unnecessary code
