annotate mercurial/upgrade_utils/actions.py @ 49218:801ef401597e

changelog-v2: mark upgrade action as changelog only We don't need to recompute the others revlog to add the changelog-v2 feature. This does not have much effect in practice as the `copies-sdc` upgrade still triggers the other revlogs. This will be fixed in the next changeset.
