This is a no-op but will be used in upcoming scudo changes that allow to change the depot size at process startup time, and as such we will no longer be able to call __scudo_get_stack_depot_size in debuggerd. We already did the equivalent change for the ring buffer size in https://r.android.com/q/topic:%22scudo_ring_buffer_size%22 Bug: 309446692 Change-Id: Icdcf4cd0a3a486d1ea07a8c616cae776730e1047
