  Modified files:
    sys/nfsclient        nfs_lock.c 
  Log:
  Add O_NONBLOCK to the vn_open_cred() flags for NFS client locking when
  opening the POSIX fifo; convert ENXIO error returns to EOPNOTSUPP.
  
  This improves handling of the case where the /var/run/lock fifo exists
  but there is no listener: we immediately return EOPNOTSUPP rather
  than blocking until a listener turns up.  This could occur during a
  diskless boot before rpc.lockd is loaded, or if the lock file persists
  across a reboot following the disabling of rpc.lockd.  This may have
  suddenly started to occur due to fifo blocking fixes--previously it
  looks like attempts to read on a fifo with no listener would time out
  due to insufficient resources.
