module: add kernel param to force disable module load
Sometimes we need to test a kernel of same version with code or config option changes. We already have sysctl to disable module load, but add a kernel parameter will be more convenient. Since modules_disabled is int, so here use bint type in core_param. TODO: make sysctl accept bool and change modules_disabled to bool Signed-off-by: Dave Young <dyoung@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
