I don't think this sysctl flag is supported by the kernel. If I understand correctly, it was provided by a 3rd-party patch. I think that Debian does still use the patch; at least on some systems that I have access to, the parameter is available. But it may not exist on other distros. https://lwn.net/Articles/673597/
