| Binder is used in Android for both communication between processes, |

| This means one Android process can call a method/routine in another |
| Android process, using Binder to identify, invoke and pass arguments |

| Binderfs is a pseudo-filesystem for the Android Binder IPC driver |
| which can be mounted per-ipc namespace allowing to run multiple |
| instances of Android. |
| Each binderfs mount initially only contains a binder-control device. |
| It can be used to dynamically allocate new binder IPC devices via |
| ioctls. |

| Default value for the binder.devices parameter. |
| |
| The binder.devices parameter is a comma-separated list of strings |
| that specifies the names of the binder device nodes that will be |
| created. Each binder device has its own context manager, and is |
| therefore logically separated from the other devices. |

| help |
| This feature builds the binder alloc KUnit tests. |
| |
| Each test case runs using a pared-down binder_alloc struct and |
| test-specific freelist, which allows this KUnit module to be loaded |
| for testing without interfering with a running system. |
