Upstream Linux Kernel Work
This page tracks my public Linux kernel contributions and mailing-list discussions.
I keep status labels conservative. Work listed as submitted, reviewed, or discussed is not necessarily merged. Merged work will be listed separately when available in maintainer trees, linux-next, or mainline.

Earlier starter patches
Earlier patches include small cleanup/spelling fixes in networking and media/staging areas. These were useful for learning the upstream process, but my current focus is kernel hardening and security-sensitive subsystems.
