As a result, the test is marked as passed while it was skipped, like below. $ ./sysfs_memcg_path_leak.sh Run as root $ echo $? 0 Users who run the test could therefore wrongly believe the test was run and passed while it was skipped. Define the value at the beginning of the test. After this patch, the exit code reflects the skip. $ ./sysfs_memcg_path_leak.sh Run as root $ echo $? 4 Link: https://lore.kernel.org/20261102144627.88843-4-sj@kernel.org Fixes: dfa3cf0bc018 ("selftets/damon: add a test for memcg_path leak") Signed-off-by: SJ Park Signed-off-by: Andrew Morton Closes: https://sashiko.dev/#/bug/linux-a0456336-0608-4fec-ac22-0ee61d1d6a91 Reviewed-by: Aveline Noir Tested-by: Aveline Noir Cc: Shuah Khan Cc: Wang Xiaolei Cc: # 6.17.x --- tools/testing/selftests/damon/sysfs_memcg_path_leak.sh | 3 +++ 1 file changed, 3 insertions(+) --- a/tools/testing/selftests/damon/sysfs_memcg_path_leak.sh~selftests-damon-sysfs_memcg_path_leak-define-ksft_skip +++ a/tools/testing/selftests/damon/sysfs_memcg_path_leak.sh @@ -1,6 +1,9 @@ #!/bin/bash # SPDX-License-Identifier: GPL-2.0 +# Kselftest framework requirement - SKIP code is 4. +ksft_skip=4 + if [ $EUID -ne 0 ] then echo "Run as root" _ Patches currently in -mm which might be from sj@kernel.org are mm-damon-sysfs-schemes-hold-damon_sysfs_lock-in-target_metric_store.patch mm-damon-core-move-static-variable-last_nr_regions-to-damon_ctx.patch mm-damon-core-move-static-variable-rotation-to-damon_ctx.patch selftests-damon-sysfs_memcg_path_leak-define-ksft_skip.patch mm-damon-core-copy-only-installed-probe-in-damon_split_region_at.patch
