Anthony, if you rework the patch to make a new .adjust_global callback in the generic scheduler interface, and a new SCHEDOP_{get,put}_global_info, I'll support merging the new scheduler. Let me know if you need any help or clarification.

The simplest thing to do would be to modify the interface to
SCHEDOP_{get,put}_info such that if you passed DOMID_INVALID (or another
"magic" domain value), it would interpret the structure as global
settings rather than per-domain settings.

The other option would be to make a SCHEDOP_{get,put}_global_info, which
would call a (newly created) .adjust_global callback through the generic
scheduler interface.

Keir: Thoughts?

I'd opt for the latter, but my preference is not that strong.
