Just a friendly reminder:
This patch has not been pushed into either the staging or master
branch of xen.git.

This is an essential patch for the new version of RTDS scheduler which
Dario and I are maintaining.
This patch won't affect other features.

It has been a while without hearing complaints from the tools maintainers.

Is it ok to push it?

If it turns out bool is prefered, I can change it and send out a new one.
But please just let me know so that we can have a complete toolstack
for the new version of RTDS scheduler.


Thanks,
