The Subject: describes what the patch does (which was obvious from the code anyway) but the changelog fails to explain *why* the change was made. You've explained "why" adequately within this discussion so I suggest you condense those words into this patch's changelog. General muse: if a reviewer asks questions regarding a patch then we should treat those questions as bug reports against the changelogs and code comments: required information is missing. So please let's go through reviewer questions as we prepare the next revision of a patchset and make sure that all those questions are fully answered,
