Description

Now that libcfs is no longer used for time keeping in user space we can now move from the current time abstraction to what the linux kernel uses for time directly. Also the APIs used by libcfs are not 2038 safe. Lastly we should move away from jiffies as much as possible to ktime since it has less issues (LU-5543) and ktime is not impacted by tickless machines.
