Subject: [Xen-devel] [PATCH v2 05/48] xen/sched: let pick_cpu return a scheduler resource
Date: Fri, 9 Aug 2019 16:57:50 +0200 [thread overview]
Message-ID: <20190809145833.1020-6-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>
Instead of returning a physical cpu number let pick_cpu() return a
scheduler resource instead. Rename pick_cpu() to pick_resource() to
reflect that change.
Signed-off-by: Juergen Gross <jgross@suse.com>
