From 1dc4bbf0b268246f6202c761016735933b6f0b99 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 17 Nov 2016 08:32:33 -0200 Subject: [PATCH] docs-rst: doc-guide: split the kernel-documentation.rst contents Having the kernel-documentation at the topmost level doesn't allow generating a separate PDF file for it. Also, makes harder to add extra contents. So, place it on a sub-dir.
