| 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 | |
| between said processes. | |

| 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. | |
