yep, I hacked existing filefrag to do something like this, the existing
format is pretty hard to glance over :)
One thing I like about xfs_bmap is that it can tell you which Allocation
Group the blocks are in; most filesystems have some concept of
sub-regions of the filesystem, such as BGs or resource groups or whatnot
- do you think there is room for this in the FIEMAP interface? Hm, or
should this just be calculated from knowing the size of the sub-regions...
