Well, no, it doesn't: 1da177e is the git tree root commit which was
created by importing the existing bitkeeper version 2.6.12-rc2 into git.
It means this code predates the git import.  You might be able to chase
it through the history tree if you want, but that only goes back as far
as bitkeeper history.
