From cb8435dc8ba33bcafa41cf2aa253794320a3b8df Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Tue, 10 May 2022 11:32:32 -0700 Subject: ext4: reject the 'commit' option on ext2 filesystems The 'commit' option is only applicable for ext3 and ext4 filesystems, and has never been accepted by the ext2 filesystem driver, so the ext4 driver shouldn't allow it on ext2 filesystems. This fixes a failure in xfstest ext4/053.
