#     modpost: return error if module is missing ns imports and MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n
#     
#     Currently when CONFIG_MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n, modpost
#     only warns when a module is missing namespace imports. Under this
#     configuration, such a module cannot be loaded into the kernel anyway, as
#     the module loader would reject it. We might as well return a build
#     error when a module is missing namespace imports under
#     CONFIG_MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n, so that the build
#     warning does not go ignored/unnoticed.
