Still I do not think this is correct way to go.

3 points for my objection:

- Most test cases are already doing the redirection for "btrfs
   subvolume" command group
   Check my patch's commit message, overall the touched ones are less
   than 25% of all the "btrfs subvolume snapshot" calls.

- Missing handling for "btrfs subvolume delete"
   Sure you can add new filters, but I do not think it's worthy just a
   new filter.

- How to enforce the filters for the future test cases?
   Good luck if you're really pushing everyone to use the new filter.
   On the other hand, it's pretty instintive to just redirect the output.
