// This namespace is where no-vendor-variant VNDK libraries are loaded for a
// vendor process. Note that we do not simply export these libraries from the
// "system" namespace, because in some cases both the core variant and the
// vendor variant of a VNDK library may be loaded. In such cases, we do not
// want to eliminate double-loading because doing so means the global states
// of the library would be shared.
//
// Only the no-vendor-variant VNDK libraries are allowed in this namespace.
// This is to ensure that we do not load libraries needed by no-vendor-variant
// VNDK libraries into vndk_in_system namespace.
