From 450f872a8e1763c883c9f723e6937b7ed223e6d3 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 17 Dec 2007 13:09:09 +0200 Subject: UBI: get device when opening volume When a volume is opened, get its kref via get_device() call. And put the reference when closing the volume. With this, we may have a bit saner volume delete.
