Instead this should be exported to userspace in units of ms (which matches the HZ=1000 used by default on RHEL systems, so it won't be a user-visible change). The parameter read/written should be translated into units of HZ in lprocfs.</p> <p>It would actually be better to have this in units of seconds, but I don't think it is possible to change <tt>lru_max_age</tt> in a compatible way. Instead, a second parameter could be added like <tt>lru_max_seconds</tt> that converts from seconds to HZ to set the same parameter, but that is not very critical compared to having constant units between clients.</p> LU-8541
