hm, this adds rather a lot of code.  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?

Thanks.
