Subject: Some kernel module options not showing up in modinfo

Hello,

I noticed that some options are not visible in the modinfo output. For
instance "modinfo lockd" reports this on my Debian sid system:

$ modinfo lockd
filename:       /lib/modules/3.11-1-amd64/kernel/fs/lockd/lockd.ko
license:        GPL
description:    NFS file locking service version 0.5.
author:         Olaf Kirch <okir@...ad.swb.de>
depends:        sunrpc
intree:         Y
vermagic:       3.11-1-amd64 SMP mod_unload modversions 
parm:           nsm_use_hostnames:bool
parm:           nlm_max_connections:uint
$

Yet I know that there are more options and the kernel source code confirms
this:
http://lxr.free-electrons.com/source/fs/lockd/svc.c#L569

Multiple other options are defined by way of module_param_call(...) like
nlm_grace_period, nlm_timeout, nlm_updport, nlm_tcpport.

Ben Hutchings (one of the Debian kernel maintainers) confirmed me that
this was unexpected and suggested me to report it to you. If you have any
questions, just ask.

Cheers,
