 drivers/gpu/drm/ttm/ttm_device.c:112: warning: Function parameter or member 'gfp_flags' not described in 'ttm_global_swapout'
 drivers/gpu/drm/ttm/ttm_device.c:112: warning: expecting prototype for A buffer object shrink method that tries to swap out the first(). Prototype was for ttm_global_swapout() instead
