Subject: [PATCH 2/4] cmdlinepart: add option to set DEVFS_PARTITION_IN_PT flag
Date: Mon, 17 Oct 2016 15:29:21 +0200	[thread overview]
Message-ID: <20161017132923.31834-3-m.grzeschik@pengutronix.de> (raw)
In-Reply-To: <20161017132923.31834-1-m.grzeschik@pengutronix.de>

With this option it is possible to flag cdev partitions, which will also
be written to the partition table of its backing device.
