Subject: [Qemu-devel] [PATCH v6 40/42] iotests: Add filter mirror test cases
Date: Fri, 9 Aug 2019 18:14:05 +0200 [thread overview]
Message-ID: <20190809161407.11920-41-mreitz@redhat.com> (raw)
In-Reply-To: <20190809161407.11920-1-mreitz@redhat.com>
This patch adds some test cases how mirroring relates to filters. One
of them tests what happens when you mirror off a filtered COW node, two
others use the mirror filter node as basically our only example of an
implicitly created filter node so far (besides the commit filter).
