Let's be realistic here - you two seem to be talking at cross-purposes,
and that will get us precicely nowhere.

Linus:	If I'm right, your "root directory" refers to the root
	directory of a particular partition. Correct?

Al:	If I'm right, your "root directory" refers to the root
	directory of the entire VFS tree. Correct?

If you can try reading each other's comments with both of the above
definitions, I think you'll see why you're clearly drifting apart from
each other in your comments.

Best wishes from Riley.
