I didn't receive patch #1 of v6 (nor of v5).Somebody had the same idea with the helper: https://lkml.kernel.org/r/YOKsC75kJfCZwySD@elver.google.com and Matthew didn't like the _unlikely() prefix. Which meant we should just move the existing helper introduced in the merge window. Patch 1/2: https://lkml.kernel.org/r/20210705103229.8505-2-yee.lee@mediatek.com
