set_normalized_timespec - set timespec sec and nsec parts and normalize
: pointer to timespec variable to be set : seconds to set : nanoseconds to set
Set seconds and nanoseconds field of a timespec variable and normalize to the timespec storage format
Note: The tv_nsec part is always in the range of 0 <= tv_nsec < NSEC_PER_SEC For negative values only the tv_sec field is negative !

timespec_trunc - Truncate timespec to a granularity : Timespec : Granularity in ns.
Truncate a timespec to a granularity. gran must be smaller than a second. Always rounds down.
This function should be only used for timestamps returned by current_kernel_time() or CURRENT_TIME, not with do_gettimeofday() because it doesn't handle the better resolution of the latter.
