/linux/Documentation/RCU/Design/Expedited-Grace-Periods/
A DExpedited-Grace-Periods.rst8 This document describes RCU's expedited grace periods.
9 Unlike RCU's normal grace periods, which accept long latencies to attain
10 high efficiency and minimal disturbance, expedited grace periods accept
20 The expedited RCU grace periods cannot be accused of being subtle,
144 periods. Neither option is acceptable in production kernels.
146 The interaction between expedited grace periods and CPU hotplug
252 periods would have abysmal scalability and problematic high-load
386 periods and carrying out their wakeups.
434 Expediting grace periods does nothing to speed things up when RCU
436 stalls just as normal grace periods do.
