Module alias could dodge this though, I guess. | "Could"? Can you show a single module that would have name matching | binfmt-[0-9a-f]*? In other words, are they ever loaded _not_ via an | alias? I understand. I was wondering if alias information is accessible in the kernel via any routine, alike find_module(). Just to get perspective about how many times request_module() would be called with the latest patch, in general installations(or distributions), how prevalent(in use) are binfmt-xxxx loadable modules?
