From ea75f7357e3a881bd1bd0db5e483fc6a8681567b Mon Sep 17 00:00:00 2001

Subject: [PATCH] ext4: Support "check=none" "nocheck" mount options
The ext2/ext3 filesystems supported "check=none" and "nocheck" as mount options
even though that was already the default behavior and it essentially did
nothing. When using ext4 to mount ext2/ext3 filesystems, that mount option
causes the mount to fail. That isn't as backward compatible as it could be,
so add support to ext4 to accept the option.
