Hi all, Today's linux-next merge of the rcu tree got a conflict in: kernel/rcu/tree.c between commit: bf8f464ee259 ("kasan: make kasan_record_aux_stack_noalloc() the default behaviour") from the mm tree and commit: 049dfe96baf9 ("rcu: Report callbacks enqueued on offline CPU blind spot") from the rcu tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc kernel/rcu/tree.c index 3885aae5f9cb,24f1cb292a92..000000000000 --- a/kernel/rcu/tree.c +++ b/kernel/rcu/tree.c @@@ -3083,9 -3083,12 +3083,12 @@@ __call_rcu_common(struct rcu_head *head } head->func = func; head->next = NULL; - kasan_record_aux_stack_noalloc(head); + kasan_record_aux_stack(head); + local_irq_save(flags); rdp = this_cpu_ptr(&rcu_data); + RCU_LOCKDEP_WARN(!rcu_rdp_cpu_online(rdp), "Callback enqueued on offline CPU!"); + lazy = lazy_in && !rcu_async_should_hurry(); /* Add the callback to our list. */
