Hi ext4 developers,


I tired to use tune2fs metadata_csum feature on my ext4 filesystem.
I got message like:
~$ sudo tune2fs -O metadata_csum /dev/sda5
tune2fs 1.42 (29-Nov-2011)
Setting filesystem feature 'metadata_csum' not supported.

Hi Anders,

You need to upgrade your e2fsprogs because metadata_csum feature is
applied on Aug this year.
