Have we established that it's worth it? And it's complex - how do poor users know what to do with this new control? This: + * = "[dD]efault | "0" - default, automatic configuration. + * = "[nN]ode"|"1" - order by node locality, + * then zone within node. + * = "[zZ]one"|"2" - order by zone, then by locality within zone seems a bit excessive. I think just the 0/1/2 plus documentation would suffice? I haven't followed this discussion very closely I'm afraid. If we came up with a good reason why Linux needs this feature then could someone please (re)describe it?
