The API introduced in this series is not a silver bullet, users are
still able to access the untrusted value (otherwise how would they be
able to validate it?). But it provides additional guardrails to remind
users that they ought to validate the value before using it. As already
stated, they can access the value directly, but to do that, they need to
explicitly call one of the untrusted_* functions signaling to
reviewers that they are reading untrusted data without validation.
this does not seem to indicate that anything is being checked at build time? is there a part of the patch that demonstrates the zero-overhead build-time checking you describe? or is your point that the rust for linux people are receptive to these concerns and other kernel devs aren't? i'm confused by "this change forces you to always be aware of that, which is something that C in the kernel does not" when the part i quoted very explicitly says it is not a silver bullet and just provides additional guardrails (which is obviously useful, i'm not contesting that)
