Subject: [PATCH v3 0/2] xen: sched: Credit1 shouldn't boost vcpus being migrated.
Date: Fri, 12 Feb 2016 17:29:10 +0100	[thread overview]
Message-ID: <20160212162338.25796.17618.stgit@Solace.station> (raw)

Hi,

take 3 of this series. Only change wrt v2 is the atomic-safeness fix in patch
2.

While there, I've also added a comment about the need for such atomic-safeness
when accessing Credit1's svc->flags.

History is here:

 v2: http://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01750.html
 v1: http://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01620.html

Thanks and Regards,
Dario
