  17 # This test assures that we can have the same provider name across multiple
  18 # probe definitions, and that the result will be the union of those
  19 # definitions.  In particular, libusdt depends on this when (for example)
  20 # node modules that create a provider are loaded multiple times due to
  21 # being included by different modules.
