  This patch supports a new sub-command 'move_range' in f2fs_io
to move a range of data blocks from source file to destination
file via F2FS_IOC_MOVE_RANGE ioctl.

It's better to wrap the long line as below?

#define move_range_help							\
"f2fs_io move_range [src_path] [dst_path] [src_start] [dst_start] "	\
"[length]\n\n"								\

Thanks,
