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.
