Subject: [PULL 1/7] qapi: add support for blkreplay driver
Date: Fri, 25 Oct 2019 15:46:05 +0200	[thread overview]
Message-ID: <20191025134611.25920-2-kwolf@redhat.com> (raw)
In-Reply-To: <20191025134611.25920-1-kwolf@redhat.com>

From: Pavel Dovgalyuk <pavel.dovgaluk@gmail.com>

This patch adds support for blkreplay driver to the blockdev options.
Now blkreplay can be used with -blockdev command line option
in the following format:
-blockdev driver=blkreplay,image=file-node-name,node-name=replay-node-name

This option makes possible implementation of the better command
line support for record/replay invocations.
