Please read linux/include/linux/init.h: /* Functions marked as __devexit may be discarded at kernel link time, depending on config options. Newer versions of binutils detect references from retained sections to discarded sections and flag an error. Pointers to __devexit functions must use __devexit_p(function_name), the wrapper will insert either the function_name or NULL, depending on the config options. */ #if defined(MODULE) || defined(CONFIG_HOTPLUG) #define __devexit_p(x) x #else #define __devexit_p(x) NULL #endif H.J.
