Well, the obvious thing to do here is block kmod if we're currently loading the same module. Otherwise it has to do some weird spinning thing in userspace anyway. We already have module_wq for this, we just need a bit more code to share the return value; and there's a weird corner case there where we have "modprobe foo param=invalid" then "modprobe foo param=valid" and we fail both with -EINVAL, but it's probably not worth fixing.
