  Modified files:
    sys/sys              mbuf.h 
  Log:
  Let M_LEADINGSPACE write into non-shared mbufs.
  A similar thing has been in -stable for weeks and is completely safe.
  
  This has very good performance implications as it saves some data
  copying, and sometimes avoids triggering performance bugs in devices
  (such as the "dc" and other Tulip clones) which do not like scattered
  data.
