I've pulled it 2-3 times now, looked at it a few times, unpulled it. drm/i915: Be wary of data races when reading the active execlists To me reads, like we avoided locking, we tried to fly too close to the sun, it burned us and we fell back to earth. Instead of not flying too close to the sun, we just stuck some bandaids on the wings. drm/i915: Remove i915_request.lock requirement for execution callbacks at least it stops opencoding an __llist_add function that was likely dubious to begin with, but I'm having trouble convincing myself this is a "fix" for anything other than we dug a hole, CI maybe coughed a bit, keep digging. drm/i915: Filter wake_flags passed to default_wake_function I replied to elsewhere, but the whole (pos->func == autoremove_wake_function) idiom just seems wrong, I'd probably have to point it out to Linus to ask what is right, but we already do it elsewhere in the file, makes me wonder who reviewed this in the first place. Like this stuff has been getting past me for years but I'm not happy about it anymore, I'm going to just be grumpy asshole going forward. If we introduced scheduler races in linux-next, I want to see reverts, and reverts only until we stopped introducing them. drm/i915: Copy default modparams to mock i915_device drm/i915: Provide the perf pmu.module are probably acceptable.

Hi Dave & Daniel, (Covering for Jani here for drm-intel-next-fixes) 5 new commits over drm-intel-next here. Fix for KASAN detected race condition and linux-next scheduler WARNs. Patch to avoid IRQ spinlock and Cc: stable PMU refcount update. CI machinery needed some kicking, so results didn't appear at first.
