From 7fcd9c3ecbf09c0a77db7ba01aac75b32fb79a93 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Thu, 2 Jul 2009 17:15:47 +0200 Subject: UBIFS: allow more than one volume to be mounted UBIFS uses a bdi device per volume, but does not care to hand out unique names to each of them. This causes an error when trying to mount more than one volumes. Append the UBI volume and device ID to avoid that.
