In linux kernel since version 6.17 (release Date: 2025-09-28)
Include benchmarks in the KUnit tests for cryptographic functions.
The benchmark results are printed to the kernel log when the
corresponding KUnit test suite runs.

This is useful for evaluating the performance of the cryptographic
functions. However, it will increase the runtime of the KUnit tests.

If you're only interested in correctness testing, leave this disabled.
