The only problem looks like the message printing.
A GC pass is triggered by the mount process, finds no
garbage to collect, and does nothing.  Perfect!

Possibilities:

1. Change nothing.  The software doesn't get confused, just the operator.

2. Add code to avoid the printk's when there are plenty of _free_ blocks.

3. Don't trigger the GC on mount unless there is something to do.
