The kernel does already do check, see dev/dkwedge/dk.c:dkwedge_add(). There is clearly the intent to catch overlaps, so some design decision (not necessary final of course) has been done before. It did just not have the full effect due to implementation bugs. Is there something like a design document, to see the big plan? best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
