Dear Arnd Bergmann:
We find a small bug here which make LTP 20170929 clock_getres01
fail. The bug is in __vdso_clock_getres() function. When argument res
is NU
ll recover it.
We verify all modifications by LTP 2017 related cases and glibc
2.26 testsuite. We plan to add it in the next version patch and
hope you can give us some comments as before.
Thanks
Vincent
