Subject: [PATCH 4/6] xenbus: process otherend_watch event at 'state' entry in xenwatch multithreading
Date: Fri, 14 Sep 2018 15:34:14 +0800 [thread overview]
Message-ID: <1536910456-13337-5-git-send-email-dongli.zhang@oracle.com> (raw)
In-Reply-To: <1536910456-13337-1-git-send-email-dongli.zhang@oracle.com>
This is the 4th patch of a (6-patch) patch set.
With this patch, watch event in absolute path pattern
'/local/domain/<domid>/device/<pvdev>/<handle>/state' can be processed in
per-domU xenwatch thread.
