Its filename was selftests-mm-soft-dirty-skip-two-tests-when-thp-is-not-available.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Chunyu Hu Subject: selftests/mm: soft-dirty: skip two tests when thp is not available Date: Mon, 30 Mar 2026 23:14:58 +0800 The test_hugepage test contain two sub tests. If just reporting one skip when thp not available, there will be error in the log because the test count don't match the test plan. Change to skip two tests by running the ksft_test_result_skip twice in this case.
