Convert the existing binder_alloc_selftest tests into KUnit tests. These tests allocate and free an exhaustive combination of buffers with various sizes and alignments. This change allows them to be run without blocking or otherwise interfering with other processes in binder. This test is refactored into more meaningful cases in the subsequent patch.

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

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.
