Its filename was selftests-mm-split_huge_page_test-skip-the-test-when-thp-is-not-available.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Chunyu Hu Subject: selftests/mm: split_huge_page_test: skip the test when thp is not available Date: Thu, 2 Apr 2026 09:45:42 +0800 When thp is not enabled on some kernel config such as realtime kernel, the test will report failure. Fix the false positive by skipping the test directly when thp is not enabled.
