In theory the definition came from fee0d486ef34c by @nc (https://reviews.freebsd.org/D30707)
It did, although that commit did not add a copyright statement to the file it was added to. I think it doesn't much matter for the trivial content in this file. We can add a @nc copyright, but I think it would be the first one in the tree.
Is nc a big contrubutor? But all the ip in this file is from nc, so the copyright is misleading...
Also, i thought FF contracts were doing spdx exclusively now
Yes, for FF-sponsored work we can use SPDX-only.
Fix copyright header and restore copyright of @nc
