Hi.  This was not considered.

I wanted to give you some quick feedback, so I tried your suggestion in the
fork path.  It seemed to fix the problem as well.

put_unaligned(timespec_to_ns(&ts), (__u64 *) &ev->timestamp_ns);

Is what I tried.

I'm on vacation tomorrow but on Thursday, if you like, I can whip up
a patch that does this and test it more thoroughly.  Is this the
direction you prefer?  What I did just now was really quick and dirty
to see if it has a shot or not but it looks like put_unaligned will
fix it too.
