2020-01-14selftests/timens: Add a test for timerfdAndrei Vagin1-0/+128
Check that timerfd_create() takes into account clock offsets. Output on success: 1..3 ok 1 clockid=7 ok 2 clockid=1 ok 3 clockid=9 # Pass 3 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 Output on failure: 1..3 not ok 1 clockid: 7 elapsed: 0 not ok 2 clockid: 1 elapsed: 0 not ok 3 clockid: 9 elapsed: 0 Bail out! Output with lack of permissions: 1..3 not ok 1 # SKIP need to run as root Output without support of time namespaces: 1..3 not ok 1 # SKIP Time namespaces are not supported Co-developed-by: Dmitry Safonov <dima@arista.com> Signed-off-by: Andrei Vagin <avagin@gmail.com> Signed-off-by: Dmitry Safonov <dima@arista.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20191112012724.250792-30-dima@arista.com
