+Creating commit links to
+The web site is meant as a grand archive of all mail
+list traffic concerning or influencing the kernel development. Storing archives
+of patches here is a recommended practice, and when a maintainer applies a
+patch to a subsystem tree, it is a good idea to provide a Link: tag with a
+reference back to the lore archive so that people that browse the commit
+history can find related discussions and rationale behind a certain change.
+The link tag will look like this:
+ Link:<message-id>
+This can be configured to happen automatically any time you issue ``git am``
+by adding the following hook into your git:
+.. code-block:: none
+ $ git config am.messageid true
+ $ cat >.git/hooks/applypatch-msg <<'EOF'
+ #!/bin/sh
+ . git-sh-setup
+ perl -pi -e 's|^Message-Id:\s*<?([^>]+)>?$|Link:$1|g;' "$1"
+ test -x "$GIT_DIR/hooks/commit-msg" &&
+ exec "$GIT_DIR/hooks/commit-msg" ${1+"$@"}
+ :
+ $ chmod a+x .git/hooks/applypatch-msg
