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.
