This isn't really on-topic for TUHS so I'll give you a longer answer by
private email. Yes, I agree that there is documentation for parts of the
code, some of which even refers to the current version. Been through a
good pile of it. Still no clue as to the entry points in namei.c.

And sorry, I wasn't clear. I wasn't talking about the code for a

It's certainly not perfect; if you'd like to suggest improvements,
again, they would be gratefully accepted, the first link I sent you
was documentation for the generic file system code, and while there is
certainly more that I'd love to see documented (improvements and bug
reports gratefully accepted), the entry points are certainly one of
the things that is quite well defined:

you can actually make a better file system, please go for it, you're
a better person than me. I've looked that that code, and it's huge, has no
clearly defined entry and exit points, and is undocumented. While I've been
too busy to deal with stuff, I found some minor bugs and a possible big
performance improvement just from trying to read the code.
Did you report those bugs and potential performance improements?
Feedback is always gratefully accepted.
As far as documentation is concerned, it's not perfect, but it's
certainly not completely undocumented:
