Sorry for disturbing, our production system(3.14 and 3.18 stable
kernel) have many tcp_fragment warnings,
the trace is same as below one which you discussed before.

But I didn't found the final solution in that mail thread, do you have
any new ideas or patches on this warning?
I think the following points to the last discussion.  We are currently using a
similar patch:

Eric, any update on your findings? or you have already pushed a fix?

Thanks,
