__GFP_ZEROTAGS is intended as an optimization: if memory is zeroed during allocation, it's possible to set memory tags at the same time with little performance impact.Perhaps you could mention this intention explicitly in the comment? Right now it still doesn't reference performance.
Sure, will do in v5. Thanks!
