fssum: seek for data before adding to the sum This change is incompatible with previous versions of fssum and changes all sums computed with the default option to include file data (-d/-D switch). To compute sums for large sparse blocks, we use SEEK_DATA before reading. To detect holes of different size, each data block is preceeded by its offset in the file. Holes are not included in the sum explicitly.
