Subject: why does skb->tstamp use getnstimeofday?
Date: Sun, 15 Jan 2012 19:11:31 +0400 [thread overview]
Message-ID: <op.v74shh18fzo5me@stalin> (raw)
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.
