Subject: [Xen-devel] [PATCH v2 02/48] xen/sched: move per-vcpu scheduler private data pointer to sched_unit
Date: Fri, 9 Aug 2019 16:57:47 +0200 [thread overview]
Message-ID: <20190809145833.1020-3-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>
This prepares making the different schedulers vcpu agnostic.
Note that some scheduler specific accessor function are misnamed after
this patch. This will be corrected in later patches.
