Horatiu's ask for more details was perfectly reasonable. Provide more details to give the distros and users an idea of the order of magnitude of the problem. Example workload and relative perf hit, anything.
For example, a workload is iperf with 128 threads, and with RPS enabled. We saw perf regression of 25% with the previous patch adding the counters. And this patch eliminates the regression.
Exactly what I was looking for, thanks. Please put that in the commit message and post v3 (feel free to add the review tags which came in for v1 in the meantime).
