  Modified:    sys/kern  vfs_bio.c
  Log:
  Correct handling of dirty pages in I/O buffers.  The case where pages
  residing in a buffer that had been dirtied by a process was being
  handled incorrectly.  The pages were mistakenly placed into the
  cache queue.  This would likely have the effect of mmaped page modifications
  being lost when I/O system calls were being used simultaneously to
  the same locations in a file.
