Subject: [PATCH 4/4] qemu-storage-daemon: Remove QemuOpts from --object parser
Date: Tue, 29 Sep 2020 19:26:49 +0200	[thread overview]
Message-ID: <20200929172649.158086-5-kwolf@redhat.com> (raw)
In-Reply-To: <20200929172649.158086-1-kwolf@redhat.com>

The command line parser for --object parses the input twice: Once into
QemuOpts just for detecting help options, and then again into a QDict
using the keyval parser for actually creating the object.

Now that the keyval parser can also detect help options, we can simplify
this and remove the QemuOpts part.
