└─>Enable all CRC functions for KUnit test
In linux kernel since version 5.10.255 (release Date: 2026-05-08)
Enable all CRC functions that have test code in CRC_KUNIT_TEST.

Enable this only if you'd like the CRC KUnit test suite to test all
the CRC variants, even ones that wouldn't otherwise need to be built.
