I think Julia suggested making 'ptr' be an expression too, and I think
she's right. Probably 'slab' should be too - there's no reason to
limit it to just one identifier.

I suspect any "ptr->timer" access anywhere between the
del_timer_sync() and the freeing should disable things.

Although hopefully there aren't any other odd cases than that one
"clear timer function by hand" one.
