From 0c4e7fa56112b0eaef0bf88b569608620e0465b8 Mon Sep 17 00:00:00 2001 From: Chunming Zhou Date: Wed, 17 Aug 2016 11:41:30 +0800 Subject: drm/amdgpu: link all shadow bo V2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit V2: 1. use mutex instead of spinlock for shadow list, since its process could sleep. 2. move list_del to bo destroy phase.
