[PATCH] ext4: clarify error messages for mounting fs w/o journal /w journal options

From: Georg Altmann
Date: Fri Feb 12 2016 - 08:53:03 EST


Previous message was hard to understand: When mounting a ext4 fs without a
journal, but a mount option that controls journaling is used, clearly state
that the fs cannot be mounted with this option because it has no journal.
