Looking for advice on getting started with kernel development professionally

Hi all,

I hope it's okay to ask this here. I understand this list is mostly
for learning and discussion. I've been working on kernel-related
projects in my spare time, including an experimental filesystem, a
block level incremental backup utility, btrfs-progs and currently I`m
working on a multithreaded disk usage analyzer like "du" but written
from scratch.

I'm really interested in contributing to the Linux kernel
professionally and while I have over 15 years of programming
experience in different areas - was wondering if anyone had advice or
knew of any opportunities - internships, contract work, or mentoring
programs.

Totally understand if this isn't the right place to ask, but I'd be
grateful for any tips or redirections.

Thank you,
Zoltan Racz.
