+Remove SafeFreePool from MemoryAllocationLib as this API's name is misleading. Its implementation only check if a pointer is NULL. If a garbage pointer is passed in, the gBS->FreePool will still ASSERT in debug build and return error code. \r

+It is recommended that module writer should keep track how a pointer is allocated and free it after use.\r
