>
> When reading the pre-compiled graph entries from OAK-1780, the TarMK uses a
> few sanity checks to verify that the graph hasn't been corrupted and that
> using it for the cleanup operation is safe.
> It turns out that one of these sanity checks ({{bytes >= count * 24 + 16}})
> is overly strict, as the minimum size limit for the graph entry is instead
> {{count * 16 + 16}}. The "24" factor applies only when sanity of the the tar
> index entry.
> The effect of this bug is not very critical, as a graph entry that fails the
> check will just be ignored with a warning and the cleanup code will fall back
> to the slower algorithm of instead reading the segment graph directly from
> the stored data segments.
