From 9ef9d51ec9ded43d03d045f623edfa9ddd6d8620 Mon Sep 17 00:00:00 2001 From: Jamie Gennis Date: Mon, 25 Feb 2013 13:37:54 -0800 Subject: [PATCH 1/6] SurfaceFlinger: fix a couple NULL fence checks This change replaces checks for a NULL fence pointer with calls to Fence::isValid. There should no longer be NULL fences.

To be correct, disconnecting a surface from a context should retain the current buffer and continue using it when reconnected. The buffer should only be canceled when the surface is destroyed. That will wait for a later change.
