From 34911fd30c6183036de67aa96e2c5a74cd43c9cf Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 20 Jul 2016 13:31:54 +0100 Subject: [PATCH] drm/i915: Rename drm_gem_object_unreference_unlocked in preparation for lockless free Whilst this ultimately wraps kref_put_mutex(), our goal here is the lockless variant, so keep the _unlocked() suffix until we need it no more. s/drm_gem_object_unreference_unlocked/i915_gem_object_put_unlocked/ Signed-off-by: Chris Wilson Link: http://patchwork.freedesktop.org/patch/msgid/1469005202-9659-7-git-send-email-chris@chris-wilson.co.uk Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/1469017917-15134-6-git-send-email-chris@chris-wilson.co.uk --- drivers/gpu/drm/i915/i915_drv.h | 10 ++++++++++ drivers/gpu/drm/i915/i915_gem.c | 10 +++++----- drivers/gpu/drm/i915/i915_gem_tiling.c | 2 +- drivers/gpu/drm/i915/i915_gem_userptr.c | 2 +- drivers/gpu/drm/i915/intel_display.c | 6 +++--- drivers/gpu/drm/i915/intel_overlay.c | 2 +- drivers/gpu/drm/i915/intel_pm.c | 2 +- 7 files changed, 22 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index ffc97c5f9d2e..3ca1acec1522 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -2327,6 +2327,16 @@ i915_gem_object_put(struct drm_i915_gem_object *obj) __deprecated extern void drm_gem_object_unreference(struct drm_gem_object *);
