Tao Su 6bb955fce0 Revert "selftests/harness: remove use of LINE_MAX" ... Patch series "Selftests: Fix compilation warnings due to missing _GNU_SOURCE definition", v2. Since kselftest_harness.h introduces asprintf()[1], many selftests have compilation warnings or errors due to missing _GNU_SOURCE definitions. The issue stems from a lack of a LINE_MAX definition in Android (see commit 38c957f070), which is the reason why asprintf() was introduced. We tried adding _GNU_SOURCE definitions to more selftests to fix, but asprintf() may continue to cause problems, and since it is quite late in the 6.9 cycle, we would like to revert 8092162335 first to provide testing for forks[2].

Revert 'commit 8092162335 ("selftests/harness: remove use of LINE_MAX")' as that came in quite late in the 6.9 cycle.
