Subject: [PATCH 1/1] e2fsck: Add percent to files and blocks feature

I need percentages to see how disk is occupied.
Used and maximum are good, but humans work better with percentages.

When my linux boots,
I haven't enough time to remember numbers and calculate.

My PC is very fast. I can only see the message for one or two seconds.

If also I would see percentages for me would be perfect.

I think that this feature is going to be good for everyone.
