__timespec64_to_jiffies

Name:The TICK_NSEC - 1 rounds up the value to the next resolution

Proto:static unsigned long __timespec64_to_jiffies(u64 sec, long nsec)

Type:unsigned long

Parameter:

Type	Parameter	Name
u64	sec
long	nsec	= nsec % TICK_NSEC; is NOT a correct resolution rounding.

= nsec % TICK_NSEC; is NOT a correct resolution rounding. = = nsec % TICK_NSEC; is NOT a correct resolution rounding. + TICK_NSEC is the time between ticks in nsec assuming SHIFTED_HZ - 1

634

If sec >= The maximum jiffie value is (MAX_INT >> 1). Here we translate that* into seconds. The 64-bit case will overflow if we are not careful,* so use the messy SH_DIV macro to do it. Still all constants. Then

If not, we bump the shift count by 1. ) >> Here are the scales we will use.
