heh, we dont have this file anymore ... as of today, right? :)

Ah, I was assuming that expedited RCU would happen before removal 
of Classic RCU.

Our general preference is to zap code.

Actually worked out nicely in this case -- the fact that Classic RCU
is no longer in -tip meant that I could dump 25% of my test cases for
expedited RCU.  ;-)

I will be posting the updated patch shortly.

/me stares at:

  $ git diff --stat -M v2.6.30..v2.6.31-rc1 | tail -1

/me corrects himself:

Okay, so the zapping of code is the divine guiding principle we've 
been following for 15 years. Ending up with a kernel that is 11 
million lines of code is a small imperfection of mankind and is to 
be fixed.

;-)  ;-)  ;-)

I guess that if 11 million lines of code is a small imperfection of
mankind, we can only be thankful that we are not tasked with dealing
with the large imperfections.  ;-)
