The patch titled Subject: selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix has been added to the -mm mm-new branch. Its filename is selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix.patch This patch will later appear in the mm-new branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Note, mm-new is a provisional staging ground for work-in-progress patches, and acceptance into mm-new is a notification for others take notice and to finish up reviews. Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. The mm-new branch of mm.git is not included in linux-next If a few days of testing in mm-new is successful, the patch will me moved into mm.git's mm-unstable branch, which is included in linux-next Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: Andrew Morton Subject: selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix Date: Tue Aug 11 07:04:40 PM PDT 2026 clarify debugfs-unavailable error message Cc: Anshuman Khandual Cc: Chengming Zhou Cc: Johannes Weiner Cc: Michal Koutný Cc: Nhat Pham Cc: Shuah Khan Cc: Tejun Heo Cc: Wilson Felipe Pereira Signed-off-by: Andrew Morton --- tools/testing/selftests/cgroup/test_zswap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/tools/testing/selftests/cgroup/test_zswap.c~selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix +++ a/tools/testing/selftests/cgroup/test_zswap.c @@ -578,7 +578,7 @@ static int test_no_kmem_bypass(const cha return KSFT_SKIP; } if (access(PATH_ZSWAP_STORED_PAGES, R_OK)) { - ksft_print_msg("mount debugfs at /sys/kernel/debug\n"); + ksft_print_msg("debugfs not mounted at /sys/kernel/debug\n"); return KSFT_SKIP; } values = mmap(0, sizeof(struct no_kmem_bypass_child_args), PROT_READ | _ Patches currently in -mm which might be from akpm@linux-foundation.org are mm-provide-vma_is_cow_mapping-and-remove-is_cow_mapping-fix.patch mm-provide-vma_is_cow_mapping-and-remove-is_cow_mapping-fix-fix.patch tools-testing-selftests-mm-test-anonymous-page-offset-merge-behaviour-fix.patch mm-page_alloc-only-update-lowmem_reserve_ratio-on-sysctl-write-fix.patch selftests-mm-use-pattern-matching-in-gitignore-fix.patch alloc_tag-add-ioctl-to-proc-allocinfo-fix.patch selftests-mm-fix-soft-dirty-kselftest-supported-check-fix.patch mm-hmmc-hmm_do_fault-suppress-sparse-warning.patch mm-hmmc-hmm_do_fault-suppress-sparse-warning-fix.patch lib-kconfigdebug-make-debug_force_weak_per_cpu-depend-on-s390alpha.patch selftests-cgroup-test_zswap-skip-test_no_kmem_bypass-if-debugfs-is-unavailable-fix.patch drivers-media-v4l2-core-v4l2-vp9c-reduce-inlining.patch
