Subject: [Qemu-devel] [PATCH v2 3/3] qemu-img: Document backing options
Date: Wed, 26 Apr 2017 15:46:49 +0200	[thread overview]
Message-ID: <20170426134649.9042-4-mreitz@redhat.com> (raw)
In-Reply-To: <20170426134649.9042-1-mreitz@redhat.com>

The create and convert subcommands have shorthands to set the
backing_file and, in the case of create, the backing_fmt options for the
new image. However, they have not been documented so far, which is
remedied by this patch.
