From bb9059d3a034d56f57e037d7866afeef18876283 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 8 Oct 2014 11:25:17 +0100 Subject: [PATCH] drm/i915: Suppress no action noise from oom shrinker If we are not able to free anything (the shrinker leaves nothing on the global object lists), do not log anything. This is useful when other subsystems are being stress-tested for their oom behaviour and i915.ko is shouting into the logs about doing nothing.
