    sys/kern             kern_subr.c uipc_mbuf.c uipc_syscalls.c 
    sys/sys              uio.h 
  Log:
  Rewrite sendfile's header support so that headers are now sent in the first
  packet along with data, instead of in their own packet.  When serving files
  of size (packetsize - headersize) or smaller, this will result in one less
  packet crossing the network.  Quick testing with thttpd and http_load has
  shown a noticeable performance improvement in this case (350 vs 330 fetches
  per second.)
  
  Included in this commit are two support routines, iov_to_uio, and m_uiotombuf;
  these routines are used by sendfile to construct the header mbuf chain that
  will be linked to the rest of the data in the socket buffer.
