Hi Tvrtko,

what about this build error? Seems to be an Xe branch conflict?


BTW, I think Danilo and I told you a few times already that we would
like to get the whole patch series into our inboxes. You seem to
exclude patches for other components, but it's important for me to see
all the other driver maintainers' RBs etc. there and be easily able to
ping those who haven't reacted yet and so on. Also quickly coyping an
mbox to test-apply something etc. etc. is easier

I guess you want to spare people from noisy mail traffic, but getting
31 patches is not a problem, those who don't care can simple ignore
them or collapse the thread in their mail program and so on.


Thanks
P.

I don't know what happened there in LKP, it appeared for the first time 
with v6. Drm_sched_scheduler_two_clients_attr looks constant to me:

static const struct kunit_attributes 
drm_sched_scheduler_two_clients_attr = {
	.speed = KUNIT_SPEED_SLOW,
};

static struct kunit_case drm_sched_scheduler_two_clients_tests[] = {
	KUNIT_CASE_PARAM_ATTR(drm_sched_scheduler_two_clients_test,
			      drm_sched_scheduler_two_clients_gen_params,
			      drm_sched_scheduler_two_clients_attr),
	{}
};

It builds fine for me but I will keep an eye on it.

I assume all important people are subscribed to dri-devel anyway so all 
patches should be in their inboxes. But I will try and remember to 
explicitly cc you two.
