Subject: skb_shared_hwstamps ability to handle 64 bit seconds and nanoseconds

Hello all,
I am not sure if this is the right list but I posted this in newbies
and got referred here.  Anyone have any insight?

I had a question regarding kernel timestamping.  I see definitions for
SO_TIMESTAMPING_NEW in networking options to allow use of time
structures containing 64bit timestamps.  However, I don't see any way
for skbuff timestamps to pass around structures with 64 bits as the
skb_shared_hwstamps use a typedef ktime_t which stacks the seconds and
nanoseconds into a single 64bit value.
I am not sure who maintains this section of the code.  Any ideas?

thanks...Greg
