Hello, Frederic,
Just realized that I could further decrease RT latency of one of my "shut up RCU on NO_HZ_FULL CPUs" patches if I relied on CPU 0 always having a scheduling-clock tick unless the entire system is idle. The trick is that I could then rely on CPU 0 to detect RCU CPU stall warnings, and remove the checking from the other CPUs.
Thoughts?
Thanx, Paul
