commit cc1de6e800c253172334f8774c419dc64401cd2e upstream. Otherwise we could try to evict overlapping userptr BOs in get_user_pages(), leading to a possible circular locking dependency. Signed-off-by: Christian König Acked-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: fix user fence handling

2015-12-16T22:48:59+00:00
