[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.
