I can update the change log to include:

$ cat timer.cocci
@@
expression E, ptr, slab;
identifier timer, rfield;
@@
(
-       del_timer(&ptr->timer);
+       timer_shutdown(&ptr->timer);
|
-       del_timer_sync(&ptr->timer);
+       timer_shutdown_sync(&ptr->timer);
)
  ... when strict
      when != ptr->timer.function = E;
(
        kfree_rcu(ptr, rfield);
|
        kmem_cache_free(slab, ptr);
|
        kfree(ptr);
)
$ spatch --dir timer.cocci . > /tmp/t.patch
$ patch -p1 < /tmp/t.patch

if you want.

The question now comes, how should you take it?

- You pull in this series directly.

- Thomas takes it and sends you a pull request (although he's been very
  quiet on this topic, even though he told me he was OK with it on IRC).

- I add it to my tree, and send you a pull request?

I'll let you choose.
