Subject: perf test: Split monolithic 'util' test suite into sub-tests
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a540f031bbbceb6e390a71eb9f7f8d65363356ba;p=thirdparty%2Fkernel%2Flinux.git

perf test: Split monolithic 'util' test suite into sub-tests

Refactor the monolithic 'util' test suite into distinct 'String
replacement' and 'BLAKE2s hash' sub-tests using the struct test_case
framework. This improves test reporting granularity and is used in a
subsequent perf test for JUnit XML test result reporting.
