Pull futex updates from Ingo Molnar:
- Standardize on ktime_t in restart_block::time as well (Thomas
Weißschuh)
- Futex selftests:
- Add robust list testcases (André Almeida)
- Formatting fixes/cleanups (Carlos Llamas)
* tag 'locking-futex-2025-12-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
futex: Store time as ktime_t in restart block
selftests/futex: Create test for robust list
selftests/futex: Skip tests if shmget unsupported
selftests/futex: Add newline to ksft_exit_fail_msg()
selftests/futex: Remove unused test_futex_mpol()
