Hi all,
In arch/i386/config.in , there is a line as follows
tristate 'Kernel support for MISC binaries' CONFIG_BINFMT_MISC
This declares CONFIG_BINFMT_MISC to have 3 possible values (y, m or n).
In fs/proc/root.c we have
#if defined(CONFIG_BINFMT_MISC) || defined(CONFIG_BINFMT_MISC_MODULE)
...
CONFIG_BINFMT_MISC_MODULE does not seem to be declared anywhere.
Is it automagically defined if CONFIG_BINFMT_MISC is set =m.?
why cant we simply do
ifeq ($(CONFIG_BINFMT_MISC), m) ...
Can anyone clarify how CONFIG_BINFMT_MISC_MODULE comes into existence.
(or point me to literature..unless I missed it in Documentation/kbuild)
Thanks in advance. All help is appreciated.
