btw., does anyone know about some reliable way to stress and measure RCU
completion performance, via some real userspace app? I think there used
to be an open-tons-of-files thing that unearthed the
RCU-completion-single-threadness bottleneck a year or two ago? Anyone
got a link to it (or to some other performance tool for RCU)?
