From 2e7ba01494ea1ec33ae7d7f5f124975818ddb825 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 9 Aug 2016 08:37:00 +0100 Subject: [PATCH] drm/i915: Remove unused i915_gem_active_peek_rcu() This was originally introduced to be used by the busy-ioctl, but in the end busy ioctl performed a different dance. Since there are no users, and no likely users, remove an unwanted chunk of the API.
