    kern - Clean up pipe filters
    
    * Do not check ki_note, just issue the KNOTE and let kq sort it out.
    
    * Remove an unmatched rel_mplock().
    
    * Take the r and w tokens for the pipe in question before poking around for
      states and sizes.
    
    * Reverse the pipe end that the write filter assumes it will receive, this
      matches the semantics of the previous .fo_poll implementation.
