    sys/kern             vfs_syscalls.c 
  Check that namecache references to the mount point are no longer present
  before unmounting a filesystem.  Forced unmounts ignore the check but will
  print a warning.
  This patch is primarily designed to prevent nullfs partitions from being
  unmounted while processes are still present within them.  The normal vnode
  check does not work for nullfs mounts since nullfs mounts do not hold any
  vnodes of their own.
  Note that this will cause a warning to be reported for the root filesystem
  when rebooting.
