utimensat() syscall was introduced from linux-2.6.22 onwards. Michael wrote the initial testcases, and, the same is being contributed to LTP under GPLv2. I worked out a patch for this. Though this is not using LTP specific libraries at the moment. But the tests run well and tests 99 separate variations. Michael has written it through itś length and breadth. I generated the code coverage (9.2%) over 2.6.25-gcov kernel, which however was not built with <make allmodconfig> option. Please see it attached along with a draft man page of utimensat(), created by Michael. Let us know how do you feel about this test. We can then go ahead and add this to LTP.
