Subject: [RFC][PATCH 2/4] sched: change the handling of credits over upper bound
Date: Fri, 05 Dec 2008 19:05:51 +0900	[thread overview]
Message-ID: <4938FCFF.5060503@jp.fujitsu.com> (raw)
In-Reply-To: <4938FC06.9080008@jp.fujitsu.com>

By applying this patch, the credit scheduler don't reset vcpu's credit
(set to 0) when the credit would be over upper bound. And it prevents a
vcpu from missing becoming active.

Best regards,
Naoki Nishiguchi
