DiskUsage probably should not scan packagefs directories at all because it will produce false disc usage numbers. Only package files takes disk space.

Replying to X512:

DiskUsage probably should not scan packagefs directories at all because it will produce false disc usage numbers. Only package files takes disk space.

I already implemented the filtering in DiskUsage. It still browse the packaged directory because it needs to access non-packaged, settings, and other shine-through directories. But for each file it checks the device it is stored on (from the dev_t in entry_ref), and ignores the ones that are in another device than the one being scanned.

I believe this should be fixed in hrev58496, having been earlier turned into a NULL dereference instead of a use-after-free in hrev58123~1.
