Hello!

Glad to see he patch here. One thing, about the subject line: it should
contains "tags", i.e., an indication of the component that the patch
affects.

So, for example, in this case, the patch touches Credit1, which means
scheduling inside Xen. So, a valid subject line could be:

 [PATCH] xen: sched: removal of redundant check in Credit

or:

 [PATCH] xen: credit: removal of redundant check

I'd remove "which adds more code clarity and performance" and put here
something like:

"In fact, the function is only called from csched_tick, which already
checks that current is not the idle vcpu."

Apart from what just said above, the patch looks good to me. Can you
send version 2 with the changelog updated?

Oh, and I see that you are both inlining in the email and attaching the
patch. I personally don't particularly mind, but that may make the life
of a committer (the person which, when the patch will have all the
Acks, will put it inside the Xen git repository) a bit more difficult.

So, this is mostly George's call, I think, but FWIW, I'd suggest you
avoid doing that. :-)

Thanks and Regards,
Dario
