BugLink: https://bugs.launchpad.net/bugs/1756311 Avoid sending scheduling-clock interrupts to CPUs with a single runnable task, and such CPUs are said to be "adaptive-ticks CPUs". This is important for applications with aggressive real-time response constraints and for computationally intensive short-iteration workloads. By default, no CPU will be an adaptive-ticks CPU. The "nohz_full=" boot parameter specifies the adaptive-ticks CPUs.
