Hi Greg,

Thanks a lot for the clarification. I had no idea of the concept of alive or "end-of-life" kernels before, sorry about that.

We wanted to apply this patch because we saw that Ubuntu continues releasing bug fixes for some of those old branches. If we see any problems in Red Hat or Ubuntu, we'll just contact them directly.

OVS's meter was only introduced since 4.15, so there is no need for kernels before that.

Thanks again, Yifeng

commit upstream 25432eba9cd8f2ef5afef55be811b010a004b5fa

This commit ("openvswitch: meter: Fix setting meter id for new entries") fixes an issue that makes OVS meter malfunction. This fix is already in upstream 4.18 and later.

It is a low risk fix, since it only passes the missed value of meter_id to new meter entries.

4.15, 4.16, and 4.17 are all long end-of-life kernels, so I don't know what we can do here with this commit.

Do you need it in 4.14? 4.9? 4.4?

Always look at the kernel.org releases page to see the currently-alive kernel versions.

thanks,
