I've applied this.  But I have to wonder why Documentation/tty exists at
all; is there any reason not to move it all under driver-api?

Thanks,

No reason at all, it should probably be moved someday.

The only reason was that I don't completely understand what "driver-api" 
should contain. To be presice, documentation of line disciplines, tty 
buffer and tty internals (which is all contained in Documentation/tty) 
doesn't belong to "driver-api" IMO. If it it preferred to be there, I 
can move it, of course.

Returning to this: staring into Documentation/index.rst and 
Documentation/driver-api/index.rst. Looking at documents/paths they 
reference, I still don't quite understand what is the rule to put the 
stuff to either of them.

What I used to decide to put the tty stuff to the root is that it's not 
only driver-api documented there. It documents also tty internals and 
implementation of some line disciplines.

So, now I'm confused why it does NOT belong to the root.

My thinking is: for the same reason that drivers/tty is not in the root.

I've been pushing for some time to get our documentation organized for
the readers, which means arranging things in terms of the expected
audience.  Much of what's in Documentation/tty looks like driver-api
stuff, so that's where I would like it to be.  If you have material for
other audiences, perhaps that material should go into a different book.

When I started doing this, "ls Documentation" would scroll on for many
pages.  We've been slowly moving away from that directory as an
unorganized dumping ground, but there is still a ways to go.

Thanks,

jon
