as i'm sure a few folks are aware, i occasionally run a script to scan the tree, looking for potentially "dead" CONFIG variables -- that is, variables of the form CONFIG_FUBAR for which there is no corresponding FUBAR in any Kconfig file.
i know there are some cleanups queued for post-2.6.22, and i'm going to run the script again after andrew releases what's queued in his tree, but if anyone is interested in checking any part of the tree before then, the script i use is here: http://fsdev.net/wiki/index.php?title=Misspelled_CONFIG_variables yes, it generates a number of false positives (would you folks *please* stop using a prefix of "CONFIG_" for your non-Kconfig variables?? argh. :-) but sometimes the output is informative: $ dead_config.sh fs ========== BEFS_RW ========== fs/befs/linuxvfs.c:776:#ifndef CONFIG_BEFS_RW fs/befs/linuxvfs.c:782:#endif /* CONFIG_BEFS_RW */ ... ========== HAS_COMPAT_EPOLL_EVENT ========== fs/compat.c:2112:#ifdef CONFIG_HAS_COMPAT_EPOLL_EVENT fs/compat.c:2155:#endif /* CONFIG_HAS_COMPAT_EPOLL_EVENT */ fs/compat.c:2182:#ifdef CONFIG_HAS_COMPAT_EPOLL_EVENT ========== KDB_MODULES ========== fs/xfs/linux-2.6/xfs_buf.h:414:#ifdef CONFIG_KDB_MODULES fs/xfs/linux-2.6/xfs_buf.c:1871:#ifdef CONFIG_KDB_MODULES ========== NCPFS_DEBUGDENTRY ========== fs/ncpfs/ncplib_kernel.c:729:#ifdef CONFIG_NCPFS_DEBUGDENTRY ========== XFS_DEBUG ========== fs/xfs/xfs.h:21:#ifdef CONFIG_XFS_DEBUG fs/xfs/Makefile-linux-2.6:23:ifeq ($(CONFIG_XFS_DEBUG),y) ... etc etc ... $ dead_config.sh drivers ... ========== 68328_SERIAL_UART2 ========== drivers/serial/68328serial.h:184:#ifndef CONFIG_68328_SERIAL_UART2 ... ========== ALMA_ANS ========== drivers/serial/68328serial.c:109:#if defined(CONFIG_M68EZ328ADS) || defined(CONFIG_ALMA_ANS) || defined(CONFIG_DRAGONIXVZ) ... ========== BLK_DEV_MAC_MEDIABAY ========== drivers/ide/legacy/macide.c:80:#ifdef CONFIG_BLK_DEV_MAC_MEDIABAY drivers/ide/legacy/macide.c:131:#ifdef CONFIG_BLK_DEV_MAC_MEDIABAY ... and on and on and tediously on. i'll do a more complete run during the next merge window, but feel free to check things out for yourself before then. rday -- ======================================================================== Robert P.
