For it to merely get loaded you only need to implement the module interface 
and put it in the right place. For something reasonable to happen the basic 
FS interface API needs to be implemented.

Auto-detection of partitions requires the identify_partition() and 
scan_partition() hooks (plus free_identify_partition_cookie(), if you use 
identify cookies that needs freeing). You haven't implemented the latter, so 
it cannot work (cf. the ReiserFS implementation for how this needs to be 
done).

Even when not implementing the *_partition() hooks, you can mount the FS 
manually using the "mount" command.
