From: Jonathan Corbet Date: Sat, 19 Nov 2016 00:21:32 +0000 (-0700) Subject: doc: Sphinxify the tracepoint docbook X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6ba7a9c8b5a6a42e8f7a7efd8345122611b535c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
