Recently I'm very confused with struct InodeCap's issued, implemented, wanted fields. I just have a preliminary understanding of them, but what's the exact difference between them? there are lots of code to reflect the relation between them. Can you explain it for me? or any documents about it? Thanks! -- best regards, Kevin Chen
