From 4ed27a5bb9bfabaf437b45aaad315f028da5a6f1 Mon Sep 17 00:00:00 2001 From: Jan Kara <jack@suse.cz> Date: Thu, 13 Feb 2020 11:16:01 +0100 Subject: [PATCH 4/5] tests: add test to excercise indexed directories with metadata_csum References: bsc#1160979 Indexed directories have somewhat different format when metadata_csum is enabled. Add test to excercise linking in indexed directories and e2fsck rehash code in this case.
