+Description: Multiple mount protection(MMP) support.
+Details    : This feature will protect the filesystem from being mounted more
+            than once simultaneously. It will also protect changes by e2fsprogs
+            to the filesystem if it is mounted. This assumes high importance
+            in a shared storage environment where multiple mounts can severely
+            corrupt the filesystem.

+Description: Add journal checksum support. (ext3 part)
+Details    : The journal checksum feature adds two new flags i.e 
+             JBD2_FEATURE_INCOMPAT_ASYNC_COMMIT and 
+            JBD2_FEATURE_COMPAT_CHECKSUM. JBD2_FEATURE_CHECKSUM flag
+            indicates that the commit block contains the checksum for
+            the blocks described by the descriptor blocks. Now commit
+            record can be sent to disk without waiting for descriptor
+            blocks to be written to disk. This behavior is controlled
+            using JBD2_FEATURE_ASYNC_COMMIT flag.
