It is quite hard to disable it these days, and even if you do, it +only saves you about 200 bytes. However, if it is disabled, lots of bugs show +up because it is almost never tested if the option is disabled. + +This is a step to eventually just remove the option entirely, which will clean +up all of the devinit* variable and function pointer options, that everyone +(myself include) ends up getting wrong eventually, causing real problems when +memory segments are removed yet we don't expect them to be. + +Cc: Geert Uytterhoeven <geert@linux-m68k.org> +Cc: Ralf Baechle <ralf@linux-mips.org> +Cc: Bjorn Helgaas <bhelgaas@google.com> +Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> + +--- + init/Kconfig | 8 +------- + 1 file changed, 1 insertion(+), 7 deletions(-) + +--- a/init/Kconfig ++++ b/init/Kconfig +@@ -1201,13 +1201,7 @@ config KALLSYMS_ALL + Say N unless you really need all symbols. + + config HOTPLUG +- bool "Support for hot-pluggable devices" if EXPERT +- default y +- help +- This option is provided for the case where no hotplug or uevent +- capabilities is wanted by the kernel.
