From 01c0aa794305ae08eb977d0719e43577e93f9ef5 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 14 Apr 2019 08:37:58 -0300 Subject: [PATCH] docs: cma/debugfs.txt: convert docs to ReST and rename to *.rst The debugfs interface for CMA should be there together with other mm-related documents. Convert this small file to ReST and move it to its rightful place. The conversion is actually quite simple: just add a title for the document. In order to make it to look better for the audience, also mark the "echo" command as a literal block. While this is not part of any book, mark it as :orphan:, in order to avoid build warnings.
