  Modified files:
    sys/kern             vfs_cache.c vfs_subr.c 
    sys/sys              vnode.h 
  Log:
  Reclaim directory vnodes held in namecache if few free vnodes are
  available.
  
  Only directory vnodes holding no child directory vnodes held in
  v_cache_src are recycled, so that directory vnodes near the root of
  the filesystem hierarchy remain in namecache and directory vnodes are
  not reclaimed in cascade.
  
  The period of vnode reclaiming attempt and the number of vnodes
  attempted to reclaim can be tuned via sysctl(2).
