Hello.
I think I've found a small bug in isofs. When it is translating
the names (reading dir entry in isofs_find_dentry()) it writes
the translated name back into the buffer (doesn't mark it dirty,
just changes the data..). Usually it doesn't matter (although
it is a bit dirty) but if you are copying the image it matters.
So I've written a patch which should solve the problem (it was
quite easy because in most of modes the name is already translated
into allocated page...).
Goodbye Honza.
