So size should be changed to u64 rather than modifying the

WARN_ON_ONCE?

Yeah, I guess so, 32-bit has to die it seems, gets in the way of

No!

1) don't use RAW unless you have to
2) you don't have to, goto 1
3) if you do anyway, ensure its properly padded

Ok, but using that struct definition on 32-bit land, will lead to non 8 byte
alignment, right?
