          timer_exit() isn't a public function, and doesn't even exist in 2.5.
          2.4 calls it internally after timers. It seems timer users need not
          do anything special.

       Another common problem is deleting timers which restart
       themselves (by calling <function>add_timer()</function> at the end
       of their timer function). Because this is a fairly common case
- which is prone to races, you can put a call to
- <function>timer_exit()</function> at the very end of your timer function,
- and user <function>del_timer_sync()</function>
- (<filename class=headerfile>include/linux/timer.h</filename>)
+ which is prone to races, you should use <function>del_timer_sync()</function>
+ (<filename class=headerfile>include/linux/timer.h</filename>)
       to handle this case. It returns the number of times the timer
       had to be deleted before we finally stopped it from adding itself back
       in.
