Umm... It would become simpler (which is a damn good thing - less PITA with update_current_cred), but it would be still needed. FWIW, dropping that support would be a Good Thing(tm), as far as I'm concerned. _Why_ do we want that, anyway, and how much userland code is able to cope with that in sane way? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
