  Modified files:        (Branch: RELENG_3)
    sys/kern             vfs_cache.c vfs_subr.c 
    sys/sys              vnode.h 
  Log:
  Limit aliases to a vnode in the namecache to a sysctl tunable
  'vfs.cache.maxaliases'  This protects against a DoS via thousands
  of hardlinks to a file wiring down all kernel memory.
