Code review comment for lp:~nick-dedekind/mir/trusted_sessions

+class TrustSession
+{
+public:
+ virtual ~TrustSession() = default;
+
+ virtual void for_each_trusted_client_process(std::function<void(pid_t pid)> f, bool reverse) const = 0;

I don't see what this function is for. It isn't used. Which is just as well because the implementation is useless:

+void ms::TrustSession::for_each_trusted_client_process(std::function<void(pid_t pid)>, bool) const
+{
+}
