Ummm... what about the root? We shouldn't add ..
to readdir in the root.
Can you also add a test case for this? Thanks

But, isn't Root the next match
here?

What I hesitated is adding "." to a root readdir

the root cause was completly different: it's not a buffer size issue here, it's the missing "." and "..". All the 201 folder appears correctly, just missing the special folders

So no, adding "." to fd_readdir of root is a bad idea, it breaks things (tests that read root).
