From 50b29d8f033a7c88c5bc011abc2068b1691ab755 Mon Sep 17 00:00:00 2001 From: Debabrata Banerjee Date: Tue, 30 Apr 2019 23:08:15 -0400 Subject: ext4: fix ext4_show_options for file systems w/o journal Instead of removing EXT4_MOUNT_JOURNAL_CHECKSUM from s_def_mount_opt as I assume was intended, all other options were blown away leading to _ext4_show_options() output being incorrect.
