Description

Today when there are blockids belonging to an older snapshot are different that that of its corresponding live file and block from snapshot file is missing , FSCK reports a blockid missing against the live file but no clue if that block id belongs to the live file or specific snapshot file path alone  .[ in the case where file in snapshot and live file system are different with some overwrite option ]. It would be nice to show a flag in the fsck output that the blockid is missing on live file or snapshot file when using -includesnapshots option.
