Alright, I'll give it a try. Perhaps in the end, there will be a few hooks that cannot be converted. If that's the case, it seems we can just provide exceptions for the return value explanations for these not unconverted hooks, maybe on the BPF side only, thus avoiding the need to annotate return values for all LSM hooks.

Thanks. Yes, while I don't think we will be able to normalize all of the hooks to 0/-ERRNO, my guess is that we can reduce the exceptions to a manageable count.
