[v4,0/2] selftests/futex: Create test for robust list

Message

André Almeida Dec. 12, 2024, 9:04 p.m. UTC

This patchset creates a selftest for the robust list interface, to track
regressions and assure that the interface keeps working as expected.

In this version I removed the kselftest_harness include, but I expanded the
current futex selftest API a little bit with basic ASSERT_ macros to make the
test easier to write and read. In the future, hopefully we can move all futex
selftests to the kselftest_harness API anyway.

This is the expected output:
    
TAP version 13
1..6
ok 1 test_robustness
ok 2 test_set_robust_list_invalid_size
ok 3 test_get_robust_list_self
ok 4 test_get_robust_list_child
ok 5 test_set_list_op_pending
ok 6 test_robust_list_multiple_elements
# Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0

Changelog
v4:
- Fixed clang warning "robust_list.c:121: converts between pointers to integer types
with different sign"

v3: https://lore.kernel.org/lkml/[e-mail]/
- Create ASSERT_ macros for futex selftests
- Dropped kselftest_harness include, using just futex test API
