From bb3c2ea224ea4e3caa35c3e63187a48e2f9dfe18 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 1 Jun 2016 09:51:21 +0800 Subject: btrfs-progs: convert-tests: Add test for backup superblock migration New convert framework uses new and simpler chunk layout, while the cost is the more complex superblock range migration logical, compared to old convert. Enhance the convert test script to create file which will takes up 2nd backup superblock space, to ensure the superblock migration is working as expected.
