Just to confirm, by "expression", you mean "madvise(0, 0, advice)"? If
so, to be consistent with the other note, perhaps best to break this
into a phrase such as:

--8<---
.BR madvise ()
called with zero for both
.IR addr
and
.IR length
will return zero iff
.I advice
is supported by the kernel and can be relied on to probe for support.
--8<---

Thanks,
Zach
