If xfs_io's utimes command cannot interpret the arguments that are given to it, it will print out "Bad value for [am]time". Detect when this happens and drop the file out of the test entirely. This is particularly noticeable on 32-bit platforms and the largest timestamp seconds supported by the filesystem is INT_MAX. In this case, the maximum value we can cram into tv_sec is INT_MAX, and there is no way to actually test setting a timestamp of INT_MAX + 1 to test the clamping. Signed-off-by: Darrick J.
