Unused code. umakedev is used within a macro but nowhere defined it seems. makedev is used as a macroname, but ifdef'ed 0. Shouldn't hurt. Maybe someone with knowledge about OSF1 emulation should decide what happens with them in the long run. > ./dev/usb/ugen.c > ./dev/usb/uscanner.c > Failure to cache result of make_dev() I'll take those. -- B.Walter BWCT http://www.bwct.de [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
