readdir looks better as fs_ops, but if it requires too

Because you chose to run userland code in the same process with the
usermode kernel

This all seems simple and elegant enough, but it does not (quite) work:
A) It still requires a new system call on the outer kernel.
*Perhaps* this could be avoided by using ptrace, which might
be simpler with this approach because the rule is simple:
just say

ptrace can support this too. It can let sbrk/mmap through, but tell

kernel first, and then let them through in a possibly modified form.
I still don't see how this

...making them appear asynchronously with respect to userland
userspace's calls to userland kernel would, yes, be difficult. (Or
anything else that lets the ptracer regain control; syscalls are just
the most convenient such thing.)
