Olaf Kirch 460f5cac1e [PATCH] knfsd: export nsm_local_state to user space via sysctl
Every NLM call includes the client's NSM state.  Currently, the Linux client
always reports 0 - which seems not to cause any problems, but is not what the
protocol says.

This patch exposes the kernel's internal variable to user space via a sysctl,
which can be set at system boot time by statd.
