15 reports on how badly fragmented a particular file might be. It makes
16 allowances for indirect blocks for ext2 and ext3 filesystems, but can be
17 used on files for any filesystem.
21 program initially attempts to get the
22 extent information using FIEMAP ioctl which is more efficient and faster.
23 If FIEMAP is not supported then filefrag will fall back to using FIBMAP.
27 Force the use of the older FIBMAP ioctl instead of the FIEMAP ioctl for
31 Use 1024 byte blocksize for the output.
34 Sync the file before requesting the mapping.
37 Be verbose when checking for file fragmentation.
