I'd be also happy to get more clean commit messages for the vDSO commits. It is more important than refining documentation because commit log is immutable. I've already stated what is wrong ATM but I'll explain it once more shortly. When writing a commit message you should always go below your expectations what reviewers already know. You want to make them easily accessible for maintainers who have to deal with dozens of patches on a daily basis. /Jarkko
