maybe it should be now:
int xe_ggtt_node_insert_balloon(struct xe_ggtt *ggtt,
struct xe_ggtt_node *node,
u64 start, u64 end)
and:
void xe_ggtt_node_remove_balloon(struct xe_ggtt *ggtt,
struct xe_ggtt_node *node)
and maybe some day later, if we decide to move balloon nodes into ggtt,
we can convert that into:
int xe_ggtt_balloon(struct xe_ggtt *ggtt,
u64 lower_start, u64 lower_end,
u64 upper_start, u64 upper_end)
and:
int xe_ggtt_deballoon(struct xe_ggtt *ggtt)
as ballooning is a 'xe_ggtt' thing that could fully implemented there
