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
