[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.
