While not causing serious issues, it's still a nuisance and can cause unintended concurrency management behaviors. Relax the threshold on machines with lower BogoMIPS. While BogoMIPS is not an accurate measure of performance by most measures, we don't have to be accurate and it has rough but strong enough correlation. * A correction in Kconfig help text. ---------------------------------------------------------------- Geert Uytterhoeven (1): workqueue: Fix cpu_intensive_thresh_us name in help text Tejun Heo (1): workqueue: Scale up wq_cpu_intensive_thresh_us if BogoMIPS is below 4000 kernel/workqueue.c | 43 ++++++++++++++++++++++++++++++++++++++++++- lib/Kconfig.debug | 2 +- 2 files changed, 43 insertions(+), 2 deletions(-)
