Hello, binder_alloc_selftest provides a robust set of checks for the binder allocator, but it rarely runs because it must hook into a running binder process and block all other binder threads until it completes. The test itself is a good candidate for conversion to KUnit, and it can be further isolated from user processes by using a test-specific lru freelist instead of the global one. This series converts the selftest to KUnit to make it less burdensome to run and to set up a foundation for testing future binder_alloc changes.
