Hi,
At the dev meeting some folks were going through
http://wiki.xen.org/wiki/XenParavirtOps#Upstream_delta_details which
includes "Suspend event channel support for faster checkpointing in
Remus FT". We weren't sure if that was ever implemented for the pvops
kernel, but we think not. I said I would highlight it to you guys in case
it isn't already on your roadmap.
Ian.

Hi Ian,
I remember Shriram has implemented it few years ago. It's
already in upstream Xen.

FYI Ian was talking about upstream Linux kernel, not upstream Xen.
And I think that wiki page concurs with what Ian said -- it's not yet in
upstream Linux kernel.
Wei.
