[Xen-devel] [PATCH v3 0/7] xen: sched: improve scalability of Credit1, and optimize a bit both Credit1 and Credit2

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Hello,

Here's v3.

 v2: https://lists.xenproject.org/archives/html/xen-devel/2017-04/msg00800.html
 v1: https://lists.xenproject.org/archives/html/xen-devel/2017-03/msg00265.html

Series has been reordered as suggested, and also all the other comments from
v2's review have been addressed.

 git://xenbits.xen.org/people/dariof/xen.git  
xenbits/rel/sched/credit1-credit2-optim-and-scalability-v3
 (yeah, messed up the branch name... :-/)
 https://travis-ci.org/fdario/xen/builds/219753675

As far as I can tell, what are now patches 6 and 3, needs George's stamp.

What is now patch 4 ("xen/tools: tracing: add record for credit1 runqueue
stealing.") may require a tools' maintainer Ack, but I'm not sure (it does,
according to get_maintainers.pl, but it's all tracing, after all...).

Thanks and Regards,
Dario
