Old mail, but I only got to read it now.

You need to use git describe --contains <hash> to see the first git tag
containing that change, E.G.:

git describe --match v3.\*  --contains  0974658da47cb399b76794057823bf3cd22acf3

(I have a linux-next remote here, so it would match on the next
tag instead unless I use --match).

E.G. this was merged 139 commits before 3.8-rc1 was tagged.
