Hi Christophe,

Looking at this again, perhaps I'm missing something. If I understand
correctly, Kconfig CONFIG_MODULE_SIG cannot be selected without
CONFIG_MODULES; also CONFIG_MODULE_SIG depends on CONFIG_MODULES, no?
So, what is present is enough right i.e. the stub when CONFIG_MODULES is
not enabled?


Kind regards,
