Daniel Vetter ff7c60c580 drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd try ... This fixes up commit e8e89622ed Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 18 22:25:11 2012 +0100 drm/ttm: fix fence locking in ttm_buffer_object_transfer which leaves behind a might_sleep in atomic context, since the fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix is to revert the above commit and only take the lock where we need it, around the call to ->sync_obj_ref. v2: Fixup things noticed by Maarten Lankhorst: - Brown paper bag locking bug. - No need for kzalloc if we clear the entire thing on the next line. - check for bo->sync_obj (totally unlikely race, but still someone else could have snuck in) and clear fbo->sync_obj if it's cleared already.
