just to be clear, all that script is doing is identifying variables of the form "CONFIG_fubar" that are being tested in *some* preprocessor directive somewhere in the tree, but for which there is apparently no corresponding entry in a Kconfig file anywhere that could cause that variable to be configured. naturally, as geert suggests, this might represent a feature that's in progress so it's clearly not a mistake. but it's a good way to trap potential problems, as in finding "GALILLEO_GT64240_ETH" which, superficially, would seem like an obvious typo no matter what: $ grep -r GALILLEO_GT64240_ETH . ./arch/mips/momentum/ocelot_g/prom.c:#ifdef CONFIG_GALILLEO_GT64240_ETH ./arch/mips/momentum/ocelot_g/prom.c:#ifdef CONFIG_GALILLEO_GT64240_ETH ./arch/mips/momentum/ocelot_g/setup.c:#ifdef CONFIG_GALILLEO_GT64240_ETH ./arch/mips/momentum/ocelot_g/setup.c:#ifdef CONFIG_GALILLEO_GT64240_ETH $ as well as what is *obviously* dead code: $ grep -rw CONFIG_KERNELD . ./sound/core/timer.c:#ifdef CONFIG_KERNELD $ grep -rw KERNELD . ./net/core/dev.c: * Bjorn Ekwall : Added KERNELD hack. the script isn't perfect -- it will generate false positives if the variable is being set elsewhere -- perhaps hardcoded in the file or defined in a Makefile. but if you're curious, just run it against your favourite subdirectory and see what comes up. rday - 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/
