origin/master 比 upstream/master 领先 n，但 HEADS 相同

如何解决origin/master 比 upstream/master 领先 n，但 HEADS 相同

我从上游 master 拉取并推送到 origin master（在 GitHub 中）。在 Github 中说这个分支比 :master 有 2624 次提交。

sdiff <(git log --oneline upstream/master) <(git log --oneline master) 去：

其中提交 WIP 是我尝试过的解决方法，而不是问题。 日志不停地往下走，我发现了 2624 个不同之处，例如这 3 个：

                                                      > 03f566bd3c 2nd try

                                                      > 3c9a3fd0d1 updated tasmanian-mismatch

如果我打开 PR 是否需要处理这些差异？在打开 PR 之前如何与上游同步。

谢谢！
