LinuxLudus: Reiserfs e block pointer zero

[Valerio Pachera]

Ho lanciato il comando reiserfsck per verificare una partizione
reiserfs e mi da il seguente output:
-------------
Replaying journal..
Reiserfs journal '/dev/hda7' in blocks [18..8211]: 0 transactions replayed
Checking internal tree..finished
Comparing bitmaps..finished
Checking Semantic tree:

No corruptions found
There are on the filesystem:
        Leaves 4418
        Internal nodes 32
        Directories 687
        Other files 7862
        Data block pointers 3520750 (545561 of them are zero)
        Safe links 0

Cosa significa (545561 of them are zero)?
Non suona molto bene....
