  SVN rev 195773 on 2009-07-19 20:25:59Z by kib
  
  When buffer write is failed, it is wrong for brelse() to invalidate
  portion of the page that was written. Among other problems, this
  page might be picked up by pagedaemon, with failed assertion in
  vm_pageout_flush() about validity of the page.
