Subject: [PATCH 12/16] Add control structures for 3-level event channel
Date: Thu, 31 Jan 2013 14:43:00 +0000 [thread overview]
Message-ID: <1359643384-29392-13-git-send-email-wei.liu2@citrix.com> (raw)
In-Reply-To: <1359643384-29392-1-git-send-email-wei.liu2@citrix.com>
The references to shared bitmap pending / mask are embedded in struct domain.
And pointer to the second level selector is embedded in struct vcpu.
