I would point here a commit which added it or a patchset.
Shell API does not have functionality to point out missing kernel git commit,
but that might change. But even without it a comment is useful.
Maybe point out d47151b79e32 ("nfs: expose /proc/net/sunrpc/nfs in net namespaces")
and whole patchset
