Subject: [PATCH 0/2] limit xen vnic max queues number to online cpu number
Date: Fri, 23 Oct 2015 15:53:58 +0800	[thread overview]
Message-ID: <5629E796.5040203__16953.2830281698$1445586965$gmane$org@oracle.com> (raw)

Currently xen vnic allowed to create lots of queues by set module param
max_queues(both netback and netfront), when queues number larger than
cpu number, it does not help for performance but need more cpu time.

This patchset limit netback and netfront max queues number to online
cpus number.

Joe Jin (2):
  xen-netback: limit xen vif max queues number to online cpus
  xen-front: limit vnic max_queues number to online cpus
