PhantomData<T>should beDeviceCopyfor allTsince it is a ZST and noTwill actually need to be copied.UnsafeCell<T>is a ABI-transparent wrapper type which should beDeviceCopyfor allT: DeviceCopy.I may throw more into this PR later but these are just the first two things I stubbed my toe on trying to improve the soundness of my path tracer kernel.
