Subject: latest scan for "bad" config variable references in kernel tree
Date: Fri, 23 Jul 2010 10:45:10 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.00.1007231040330.958@lynx> (raw)
as of 2.6.35-rc6, i ran another scan of the tree, looking for "bad"
config variable references, as in, preprocessor tests of CONFIG_
variables that aren't defined in any Kconfig file that i can see.
it's all broken down by directory and subdirectory:
http://www.crashcourse.ca/wiki/index.php/Badref_CONFIG_variables
as an example, here's what showed up under drivers/mmc:
>>>>> MMC_EMBEDDED_SDIO
drivers/mmc/host/msm_sdcc.c:1148:#ifdef CONFIG_MMC_EMBEDDED_SDIO
>>>>> MMC_MSM7X00A_RESUME_IN_WQ
drivers/mmc/host/msm_sdcc.h:238:#ifdef CONFIG_MMC_MSM7X00A_RESUME_IN_WQ
drivers/mmc/host/msm_sdcc.c:1060:#ifdef CONFIG_MMC_MSM7X00A_RESUME_IN_WQ
as in, there's a test for "CONFIG_MMC_EMBEDDED_SDIO" when there is
no definition of such a variable in a Kconfig file.
more scanning coming later, but that page covers the whole tree
looking for just that property.
