10 Binder is used in Android for both communication between processes,
11 and remote method invocation.

13 This means one Android process can call a method/routine in another
14 Android process, using Binder to identify, invoke and pass arguments
15 between said processes.

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

47 Default value for the binder.devices parameter.
48
49 The binder.devices parameter is a comma-separated list of strings
50 that specifies the names of the binder device nodes that will be
51 created. Each binder device has its own context manager, and is
52 therefore logically separated from the other devices.

59 This feature builds the binder alloc KUnit tests.
60
61 Each test case runs using a pared-down binder_alloc struct and
62 test-specific freelist, which allows this KUnit module to be loaded
63 for testing without interfering with a running system.
