[Xen-devel] [PATCH v4 0/6] xen: sched: fix locking of {insert, remove}_vcpu()

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Hi,

This series, improves how inserting vCPUs in schedulers runqueues is done,
including fixing a couple of bugs, and paving the way for more improvement in
Credit2 runqueue handling (will be submitted as a separate series).

v3 is here:
 http://lists.xenproject.org/archives/html/xen-devel/2015-10/msg03278.html
 Message-Id: <20151029225158.25219.4625.stgit@xxxxxxxxxxxxxx>

Only patch 1 really changed from v3, and patches 1 and 2 are the only one that
seem to me to be missing suitable Ack-s.

There is a git branch for this series here:
 git://xenbits.xen.org/people/dariof/xen.git  rel/sched/fix-vcpu-ins-rem-v4

Regards,
Dario
