+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.
