[PATCH] knfsd: hide use of lockd's h_monitored flag
This patch moves all checks of the h_monitored flag into the nsm_monitor/unmonitor functions. A subsequent patch will replace the mechanism by which we mark a host as being monitored. There is still one occurence of h_monitored outside of mon.c and that is in clntlock.c where we respond to a reboot. The subsequent patch will modify this too.
