From db37c8c017ebef8f241420dda071940957d4bbe5 Mon Sep 17 00:00:00 2001 From: Wang Dong <dongdwdw@linux.vnet.ibm.com> Date: Wed, 26 Oct 2016 04:22:47 +0200 Subject: [PATCH] libparted/dasd: update and improve fdasd functions Update the fdasd_anchor_t data structure and the fdasd_cleanup() function. Also correct vtoc_changed and vlabel_changed accounting because they are important to rewrite vtoc to save the changes.
