selftests/timens: timerfd: Use correct clockid type in tclock_gettime()

2025-05-09T19:12:57+00:00

tclock_gettime() is a wrapper around clock_gettime(). The first parameter of clock_gettime() is of type "clockid_t", not "clock_t". Use the correct type instead.

selftest/timerns: fix clang build failures for abs() calls

2024-07-05T19:21:48+00:00

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...clang warns about mismatches between the expected and required integer length being supplied to abs(3). Fix this by using the correct variant of abs(3): labs(3) or llabs(3), in these cases.
