From: Chunming Zhou Date: Wed, 17 Aug 2016 03:41:30 +0000 (+0800) Subject: drm/amdgpu: link all shadow bo V2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0c4e7fa56112b0eaef0bf88b569608620e0465b8;p=linux-beck.git drm/amdgpu: link all shadow bo V2 V2: 1. use mutex instead of spinlock for shadow list, since its process could sleep. 2. move list_del to bo destroy phase.
