Subject: [Qemu-devel] [PULL 15/36] iotests: teach FilePath to produce multiple paths
Date: Fri, 16 Aug 2019 19:12:57 -0400
Message-ID: <20190816231318.8650-16-jsnow@redhat.com> (raw)
In-Reply-To: <20190816231318.8650-1-jsnow@redhat.com>

Use "FilePaths" instead of "FilePath" to request multiple files be
cleaned up after we leave that object's scope.

This is not crucial; but it saves a little typing.
