[$] Linking commits to reviews

In a talk in the refereed track of the 2017 Linux Plumbers Conference,Alexandre Courouble presented the email2git tool thatlinks kernel commits to their review discussion on the mailing lists. Email2gitis a plugin for cregit, which implements token-level history for a Git repository; we covered a talk on cregit just over one yearago. Email2git combines cregit with Patchwork to linkthe commit to a patch and its discussion threads from any of the mailinglists that are scanned by patchwork.kernel.org. The resultis a way to easily find the discussion that led to a piece of code-or evenjust a token-changing in the kernel source tree.
