We use sysctl_size twice after that call. If it's not constant, chances
are that it has changed. Shouldn't we revert to the original value, or
should we use the returned value in the subsequent calls?
I've seen that warning and I considered that patch, but I didn't have a
chance to check the correctness of the change. Just silencing the
warning is not good. We should actually make sure that the problem is
fixed.

That's good.

Casts to remove "const" look like hacks to me. Again, it's better to
keep a warning that to have such code.
