    kernel - swapcache - Fix snocache and cache flags propagation, fix PG_NOTMETA
    
    * The namecache was not always propagating the snocache and cache
      chflags flags.  Now it is.  However, the flags no longer propagate
      across mount points.
    
    * The vm_page PG_NOMETA flag was being improperly applied to regular
      files.  It only applies to VCHR vnodes.
    
    * blogbench tests show significant improvement but swapcache is still
      missing some data or meta-data somewhere.
