I just checked this, and it seems like GitHub is a bit weird about tracking these. It didn't show up on my profile at all until I just now forked[0] torvalds/linux on GitHub. Now it shows up on my profile on May 9th (author date), but the link to the commit is broken, because repository authors page it points to filters on the commit date, not the author date.

Broken link points here and shows no commits: https://github.com/torvalds/linux/commits?author=vkoskiv&sin...

If I correct the date range to include the maintainer commit date (May 15th), the commit shows up: https://github.com/torvalds/linux/commits?author=vkoskiv&sin...

Also strange that if I only filter on author[1], nothing shows up. Though I suspect that dataset might only be updated periodically.
