The main changes in this series are to refactor shared tracing and assertion helpers into a common file, unify both pkey selftests on pkey_assert() and per-test tracing for consistent diagnostics, and add missing mmap() return checks with MAP_FAILED used throughout for readability and consistency.
Hongfu Li (4): selftests/mm: move pkey selftest helpers to pkey_util.c selftests/mm: unify pkey sighandler selftest assertions and tracing selftests/mm: use pkey_assert on clone_raw failure in pkey test selftests/mm: add missing mmap() return checks in pkey tests tools/testing/selftests/mm/pkey-helpers.h | 5 +- tools/testing/selftests/mm/pkey-powerpc.h | 2 +- .../selftests/mm/pkey_sighandler_tests.c | 110 +++++++++--------- tools/testing/selftests/mm/pkey_util.c | 86 ++++++++++++++ tools/testing/selftests/mm/protection_keys.c | 95 ++------------- 5 files changed, 152 insertions(+), 146 deletions(-) --- v4: - Base changes on top of the latest mm-unstable branch. - Split the first patch into three: patch 1: move pkey selftest helpers to shared code; patch 2: unify sighandler selftest assertions and per-test tracing; patch 3: use pkey_assert() on clone_raw() failure. - Use ksft_exit_fail_perror() in main() for mmap() failure. v3: - Use pkey_assert() for remaining sigaction() and clone_raw() error checks for consistency. v2: - Update commit message - Move shared tracing and assertion helpers to a common file, replace assert() with pkey_assert() in sighandler tests - Drop assert() from main() in protection_keys.c and add a proper error message instead. - Link to v1: https://lore.kernel.org/all/[email protected]/ -- 2.50.1
