This looks good but I think there's room for improvement. Are there any 
mount options which apply to a subvolume only?

And while I see space_cache having the "permanent" annotation in its 
description, I see something similar missing for e.g. the inode_cache, ssd, 
etc. descriptions. Something that says "not permanent, must be given each 
time".

Anyone willing to eloberate on this? I'd offer to contribute this to the 
wiki.

Thanks,
Kai
