Re: [Xen-devel] Xen Scheduler sedf problem.

Hmm -- looks like perhaps some of the changes we made to the schedule
ops stuff (specifically wrt when domain and vcpu data callbacks are
made) didn't get propagated to the SEDF scheduler.  I can reproduce it
locally, so I'll take a look at it tomorrow.  Thanks for getting back
on this, Gustavo.
