Robert Watson 847b14bd3c 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.
