Dave Airlie 5024307986 ttm/bo: add an API to populate a bo before exporting. ... While discussing cgroups we noticed a problem where you could export a BO to a dma-buf without having it ever being backed or accounted for. This meant in low memory situations or eventually with cgroups, a lower privledged process might cause the compositor to try and allocate a lot of memory on it's behalf and this could fail. At least make sure the exporter has managed to allocate the RAM at least once before exporting the object. This only applies currently to TTM_PL_SYSTEM objects, because GTT objects get populated on first validate, and VRAM doesn't use TT.
