there's lots of that sort of thing in the kernel -- the only point i'd make is that it seems typical to reserve the prefix "CONFIG_" strictly for those variables that are set via Kconfig files. it just makes the namespace cleaner, that's all. otherwise, that variable is going to come up continually in any script like mine that's searching for possible dead Kconfig variables. > > ========== IP_PIMSM ========== > > net/ipv4/ipmr.c:#define CONFIG_IP_PIMSM 1 as is this one, etc, etc. rday -- ======================================================================== Robert P.
