28	  Binderfs is a pseudo-filesystem for the Android Binder IPC driver
29	  which can be mounted per-ipc namespace allowing to run multiple
30	  instances of Android.
31	  Each binderfs mount initially only contains a binder-control device.

43	  that specifies the names of the binder device nodes that will be
44	  created. Each binder device has its own context manager, and is
