Hi all ,
Just a quick question on Jiffies , I just started reading about the linux kernel internals , and see that jiffies (which hold the time since boot-up of the machine) is a 32 bit variable . approximately capable of storing .. 50 days for a HZ value of 100 , As embedded systems are capable of running 24x7 for days together , how is this roll over handled in the kernel ?
