  Modified files:
    sys/vfs/nullfs       null_vfsops.c null_vnops.c 
  Log:
  Fix an endless recursion and double fault which could occur when accessing
  a filesystem mounted via nullfs where the mount itself used a path through
  another nullfs filesystem.
  
  The forwarding nullm_vfs mount pointer must be set to the actual mount
  point and not the governing nullfs.  Any read-only status from the governing
  nullfs mount will still be inherited.
