Is this btrfs scrub script still viable?

[Christian Dysthe <christian@xxxxxxxxxxx>]

Hi,
For years i've used this script to scrub btrfs volumes on a schedule:

http://marc.merlins.org/linux/scripts/btrfs-scrub

I realized it hasn't been updated in years while both Linux and btrfs
have been through numerous updates and improvements. So I was
wondering if this script is still viable or do I have to look for something 
more 
up to date? This script works as intended as far as I can see, but maybe
that's not far enough?
