From 014b34409fb2015f63663b6cafdf557fdf289628 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 16 Jan 2013 15:58:34 +1000 Subject: [PATCH] ttm: on move memory failure don't leave a node dangling if we have a move notify callback, when moving fails, we call move notify the opposite way around, however this ends up with *mem containing the mm_node from the bo, which means we double free it. This is a follow on to the previous fix.
