└─>KUnit Test for integer hash functions
In linux kernel since version 5.2 (release Date: 2019-07-07)  
Enable this option to test the kernel's string (<linux/stringhash.h>), and
integer (<linux/hash.h>) hash functions on boot.

KUnit tests run during boot and output the results to the debug log
in TAP format (https://testanything.org/). Only useful for kernel devs
running the KUnit test harness, and not intended for inclusion into a
production build.

For more information on KUnit and unit tests in general please refer
