Is https://wiki.ubuntu.com/KernelTeam/KernelMaintenance still correct?

Hi Nigel,

this looks like you added those files. But those should not. And, yes, the
document is outdated here for newer releases (Hardy would sill work that way).
In essence for newer releases a "debian/rules clean" re-creates all those files
as they are not tracked (kept) in git anymore.

For recent series, just

1) change the abi number in debian.master/changelog (for the master branch)
2) git add debian.master/changelog
3) git commit -s -F debian/commit-templates/bumpabi
4) fakeroot debian/rules clean (this is just for your build or creating the
   package)

If you look at the output of a full build, the abi checker is printing some more
elaborate info about it. Otherwise you would need to resort to compare the abi
files with something like meld.
