Subject: [PATCH v2 0/2] xen: sched/cpupool: more fixing of (corner?) cases
Date: Fri, 17 Jul 2015 15:35:46 +0200 [thread overview]
Message-ID: <20150717133013.29612.53960.stgit@Solace.station> (raw)
Hi all,
Here's v2 of this series. v1 is here:
http://lists.xen.org/archives/html/xen-devel/2015-07/msg00647.html
As a quick recap, this is aimed at avoiding an host crash during shutdown or
suspension, it in the following cases:
- when the boot cpu (i.e., most of the times, cpu 0) is not assigned to any
cpupool,
- when a (non default) cpupool only has one cpu (and that is not the boot
cpu).
v1 was bigger, because of some preparatory/mechanical chages, which have been
applied already, so here's what remains.
Patch 2 is fully acked. Patch 1 won Juergen's ack, during v1, but I'm avoiding
sticking it there, as it changed a little bit, while addressing George's
comments.
Best Regards,
Dario
