You're probably looking for the command git log -S functionname a.k.a. the git pickaxe. That will show you all of the commits that added or removed a line containing the name you're interested in, and you can then check just those changes to see what compatibility may have changed. To find out what kernel release one of those commits went into, you can use git describe <sha1-hash> and it will report the last tagged kernel version before that commit was added.
