On a related note - the FIEMAP patches to filefrag also include a new
output format that is much more useful, IMHO. The new format is like:
{filename}
ext: [logical start.. end kB]: phys start..end kB : kB:lun: flags
0: [ 0.. 30207]: 401416.. 522251: 120828: 0 :
1: [ 30208.. 60927]: 532480.. 655359: 122880: 0 :
2: [ 60928.. 121855]: 790536.. 916484: 125948: 0 :
Hopefully Kalpak will be able to post the updated patches here soon.
Cheers, Andreas
