No objections to any of this.  I love the idea of being able to write
filesystems in Rust.  I just think it would go more smoothly if
linux-fsdevel were involved more closely so people at least have the
option of being able to follow design decisions, and hopefully influence
them.  That goes both ways, of course; I hardly think our current
operations structures are the optimum way to implement a filesystem,
and having fresh eyes say things like "But that shouldn't be part of the
address_space_operations" can impel better abstractions.

I will send the patches to fsdevel then!

As for following development closely and design decisions, we have
been doing it in GitHub so far pre-merge, so the easiest until the
merge (for us) would be to ping you there. We can also send you copies
of the `fs` related patches too if you would like that. I would highly
recommend joining the monthly informal calls too.

(I appreciate the kind answer, by the way!)

The obvious answer is to split out the 'fs module' into its own patch
;-)  I presume it was part of the kernel crate which would have been
either patch 17 or 11 in that series?

Yeah, patch 17, exactly (patch 11 is the `alloc` import). I have asked
Konstantin privately about them.

In any case, I will split the patches further for v9 which should help.

Meanwhile, you can also see the `fs` module here, if you are curious:
