v2:
- split up patch into logical changes
- simplify copy_array, which can use ksize() directly
v1: https://lore.kernel.org/all/20221018090550.never.834-kees@kernel.org/

Hi,

Here's the next version of removing the BPF verifier's dependency on the
side-effects of ksize(), so we can remove the special handling needed
for KASAN, UBSAN_BOUNDS, nor FORTIFY_SOURCE in ksize().

Thanks,

-Kees
