[Xen-devel] [PATCH v3 0/5] The 'null' Scheduler

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Hello,

Here it comes version 3 of this patch series.
Previous iterations:
 v1: https://lists.xen.org/archives/html/xen-devel/2017-03/msg02316.html
 v2: https://lists.xen.org/archives/html/xen-devel/2017-04/msg01027.html

Git branch:
 git://xenbits.xen.org/people/dariof/xen.git  rel/sched/null-sched-v3
 https://travis-ci.org/fdario/xen/builds/219658242

I have applied all the comments from George's review of this morning.

I have tested the case where a pCPU becomes free and there are vCPUs in the
waitqueue, but some can't be assigned to it, because of their affinity, and it
works.

The series seems to have all the necessary Acked and Reviewed by tags, with the
only exception of patch 4.

Thanks and Regards,
Dario
