Subject: [PATCH 0/2] fixes to the hypervisor ubd thread
Date: Mon, 16 Mar 2020 20:45:05 -0400 [thread overview]
Message-ID: <20200317004507.1513370-1-krisman@collabora.com> (raw)
Hi,
While debugging a somewhat related issue, I ran into two issues I
believe can cause the hypervisor to write garbage to the pipe.
This was find by visual inspection and is only slightly tested. It
seems to partially some the problems my test case shows.
Please, let me know what you think
