From 9a298b2acd771d8a5c0004d8f8e4156c65b11f6b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 24 Mar 2009 12:23:04 -0700 Subject: drm: Remove memory debugging infrastructure. It hasn't been used in ages, and having the user tell your how much memory is being freed at free time is a recipe for disaster even if it was ever used.
