That sounds sensible, but it would seem to require defining some 'small enough that it cannot fail' size, either statically or via some getconf-like interface, so that code is only relieved of the obligation to check if the size is below the limit. Then kernels that can't enforce that limit have to panic at boot. Did you mean all that, or something else?
