That's a little too trite of an answer to be useful.

Immediately after the return of del_timer(&timer), I expect
 - kfree(timer.data) is safe
 - the timer.function() code may be immediately be 'rmmod'ed

Specifically, I expect that if the timer.function() will not be
running on another processor when del_timer(&timer) returns.  If this
doesn't hold true, the timer.function() might still be in the function entry
phase and entire timer.function() could be run after del_timer() has
nominally finished.  And if that's acceptable behavior, I have a new version
of del_timer() that's very small and fast ;->.
