Well, things evolve and we've become much more careful about changelogs over time. It still gets quite a lot of time to push back on changelogs even these days though. People still keep forgetting that "what" is not as important as "why" because the former is usually quite easy to understand from reading the diff. The intention behind is usually what gets forgotten after years. I guess people realize this much more after few excavation git blame tours. > > Signed-off-by: Michal Hocko <mho...@suse.com> > > Reviewed-by: Oscar Salvador <osalva...@suse.de> Thanks! -- Michal Hocko SUSE Labs
