[PATCH v2 0/5] binder: Set up KUnit tests for alloc

[Tiffany Yang <ynaffit@google.com>]

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 unit testing future binder_alloc changes.

Thanks,
Tiffany
