+Subject: [PATCH] Doc: Generate ids for audit_events using docname
+
+This patch generates ids for audit_events using the docname so the id is
+not global but depend on the source file. This make the doc build
+reproducible with multiple cores because it doesn't which file is parsed
+first, the id for audit_events will always be consistent independently
+of what file is parsed first.
