  Modified files:
    sys/kern             vfs_subr.c 
  Log:
  When the softdep conversion took place, the periodic vfs_msync() from
  update got lost.  This is responsible for ensuring that dirty mmap() pages
  get periodically written to disk.  Without it, long time mmap's might not
  have their dirty pages written out at all of the system crashes or isn't
  cleanly shut down.  This could be nasty if you've got a long-running
  writing via mmap(), dirty pages used to get written to disk within 30
  seconds or so.
