Hi Roland

Jack looked on this comment/code and he says that the active flag is used
to prevent re-scheduling the timer from inside the timer handling routine.

In the kernel, the comment header in the source file for del_timer_sync
explicitly states that re-scheduling the timer must be prevented,
or the sync is useless:Callers must prevent restarting of the timer, 
otherwise
this function is meaningless

So we believe that code should remain.

Or.
