Just for check - these modules should be loaded on sys_mount()?
In this case it should be prefixed with 'fs-'.
Look: do_new_mount() calls get_fs_type() which does request_module():

Otherwise, it will fail to autoload these modules on mount().
So, what is the expected call-path for autoloading nfs modules?
We shouldn't really care, because modules load is performed by modprobe
via UMH,
and looks like modprobe handles these types of module requests properly.
I tested the patch, it works.
