git-commit-template

• 可以通过git config --global commit.template template.file来配置特定的commit log，template.file为模板。
• 可以通过scripts/checkpatch.pl [patch or source file]来检查格式是否正确。

• linux kernel的commit log建议使用如下模板：

  Short (50 chars or less) summary of changes
  
  More detailed explanatory text, if necessary.  Wrap it to
  about 72 characters or so.  In some contexts, the first
  line is treated as the subject of an email and the rest of
  the text as the body.  The blank line separating the
  summary from the body is critical (unless you omit the body
  entirely); tools like rebase can get confused if you run
  the two together.
  
  Further paragraphs come after blank lines.
  
    - Bullet points are okay, too
  
    - Typically a hyphen or asterisk is used for the bullet,
      preceded by a single space, with blank lines in
      between, but conventions vary here
