From a39d7efc6200d05b9ca3cfeec5dd82f6dd03f4e8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 24 Apr 2012 18:22:52 +0100 Subject: [PATCH] drm/i915: Remove i915_gem_evict_inactive() This was only used by one external caller who would just be as happy with evict-everything, so perform the replacement and make the function private. In the process we note that unbinding the inactive list should not fail, and make it a warning instead.
