Hello everyone.

struct sk_buff has a field tstamp, which is used for high resolution rtt  
calculation.
All operations with this field are done directly or indirectly via ktime_*  
interface,
which uses getnstimeofday function.
My question is why does skb->tstamp use getnstimeofday?
Isn't it better to use getrawmonotonic, where we are not inetrfered with  
ntp,  for rtt calculation?

Thank you.
