But yeah, maybe one has to be more careful of filtering these failures out
then.
Perhaps this is something that needs considering in the ABI, so
userspace can reasonably figure out if it failed to configure whatever
is being configured due to a missing feature (in which case it should
fall back to not using that feature somehow) or due to it messing
something else up? We might be happy with the tests being version
specific but general userspace should be able to be a bit more robust.
Yeah, the whole prctl() ship has sailed, unfortunately :(
