kernel control flow integrity (kcfi)

hello Hackers,
I want to work on the Freebsd idealist project KCFI (kernel control
flow integrity), I am new in this community and want to be involved in
the Freebsd community and become a contributor.
so I want to know if this project is already done or if someone is
working on it.
if no one working on this project so how can I start work on this project?
I am interested in compiler or kernel dev.

thanks
