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,
140 The expedited nature of expedited grace periods require a much tighter
142 grace periods. In addition, attempting to IPI offline CPUs will result
144 periods. Neither option is acceptable in production kernels.
