From 0a4ba02c3d711f0160769d6b8f8cd056a3919ad9 Mon Sep 17 00:00:00 2001 From: Martin Andersson Date: Fri, 1 Mar 2013 22:34:28 +0100 Subject: winsys/radeon: Only add bo to hash table when creating flink The problem is that we mix bo handles and flinked names in the hash table. Because kms type handles are not flinked they should not be added to the hash table. If we do that we will sooner or later get a situation where we will overwrite a correct entry because the bo handle was the same as a flinked name. Note: this is a candidate for the stable branches.
