I haven't had a chance to work on this much myself. My understanding
is that igb has had the barriers updated, but I don't think any of the
other drivers have been worked over yet.
Unfortunately, I have recently changed jobs and I no longer have the
hardware to test my changes. I thought that you wanted to handle this
yourself.
I haven't seen any follow ups. I wanted to double check.
I worked with several architecture leads on 4.17. All architectures
support the updated barrier semantics now. It is time to clean up the
network drivers.
