Subject: [PATCH] ext4: bad mount opts in no journal mode
Date: Thu, 11 Apr 2019 17:49:17 -0400 [thread overview]
Message-ID: <20190411214917.1899-1-dbanerje@akamai.com> (raw)
Fixes:
commit 1e381f60dad9 ("ext4: do not allow journal_opts for fs 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. I don't see why this or
other journal related flags should be removed from s_def_mount_opt
regardless, it is only used for comparison to display opts, and we
already made sure they couldn't be set.
