Its filename was selftests-mm-emit-tap-header-and-use-tap-skip-in-mremap_test.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: Song Hu Subject: selftests/mm: emit TAP header and use TAP skip in mremap_test Date: Tue, 25 Aug 2026 16:57:55 +0800 mremap_test calls ksft_set_plan() without ksft_print_header(), and its get_mmap_min_addr() skip path uses a bare exit(KSFT_SKIP) that prints no TAP line, so its output is not valid KTAP. Add the header and switch the skip to ksft_exit_skip(). Also fix two more KTAP compliance issues spotted in review: - get_mmap_min_addr() calls strerror(errno) after fclose(), which may clobber errno; save errno before fclose() instead. - Some ksft_*() messages embed "\n\t", so the text after each embedded newline is printed without the "# " prefix. Split those into separate messages. And cache mmap_min_addr in main() before ksft_set_plan(), so that the skip paths in get_mmap_min_addr() are taken before the plan is set; a skip after the plan leaves the run with fewer tests than planned.
