From d6ba7a9c8b5a6a42e8f7a7efd8345122611b535c Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 18 Nov 2016 17:21:32 -0700 Subject: [PATCH] doc: Sphinxify the tracepoint docbook Convert the tracepoint docbook template to RST and add it to the core-api manual. No changes to the actual text beyond the mechanical formatting conversion.
