In FreeBSD we have a long history of including metadata in commit messages (bug reference, sponsorship information, reviewer list), and introduced Phabricator for code reviews a while ago. So you can easily find Foundation-sponsored commits and for many of them observe the review history.

If using the git mirror a command like git log --since=2016-01-01 --grep 'Sponsored by.*FreeBSD Foundation' will show the Foundation-sponsored commits in 2016.

Here are a few recent examples: r310702 btxldr: process all PT_LOAD segments, not just the first two https://reviews.freebsd.org/D8929 This was a tiny change of mine, removing an 18 year old assumption to allow us to build the FreeBSD base system with LLVM's LLD linker. Reviewed by a Foundation employee and a FreeBSD (and Illumos) community member.

r310617 Make knote KN_INFLUX state counted https://reviews.freebsd.org/D8898 Reviewed by a FreeBSD developer working at Isilon.

r310371 bhnd: remove srand() to ensure deterministic output https://reviews.freebsd.org/D8857 Another one of mine as part of the Reproducible Builds effort. Reviewed by the original author of the affected driver.

These are small, uncontroversial fixes, but demonstrate the approach the Foundation strives to take with all development work. Also being able to drive longer-term projects and maintain subsystems over long timescales is a significant advantage of having funded developers on staff.

r310154 Add support to read the _CLS entry if it's present https://reviews.freebsd.org/D8721 A commit from a Foundation project grant recipient, part of adding ACPI support along with the FreeBSD/arm64 porting effort. Reviewed by a long-time FreeBSD committer and core team member. The Foundation drove the overall arm64 porting effort. Cavium (an ARM CPU licensee) and ARM helped contribute to the initial porting effort, which was generally reviewed with a similar approach.

r301172 Import NetBSD's blacklist source from vendor tree https://reviews.freebsd.org/D5912 The Foundation provided a grant to port NetBSD's blacklistd daemon to FreeBSD. The initial work here was reviewed by an idependent, long-time FreeBSD committer.

The Foundation's development projects have no special status - work is still subject to the communities norms and standards. If there were to be a dispute over a proposed project or change the final authority rests with the elected core team. (The current core team includes some Foundation members, but a minority position.)
