78 o "c" is the count of grace periods that this CPU believes have
81 which has been offline through 16 RCU grace periods. It is not
82 unusual to see offline CPUs lagging by thousands of grace periods.
83 Note that although the grace-period number is an unsigned long,
87 o "g" is the count of grace periods that this CPU believes have
90 has already reported a quiescent state for the last RCU grace
95 for the current grace period. It is possible for "pq" to be
99 yet reported for this grace period, or (3) both.

265 new expedited grace period succeeded.
283 o "completed" is the number of grace periods that have completed.
286 that the corresponding RCU grace period has completed.
288 o "gpnum" is the number of grace periods that have started. It is
291 the corresponding RCU grace period has started.
293 If these two fields are equal, then there is no grace period
295 if the two fields differ (as they are above), then an RCU grace
298 o "age" is the number of jiffies that the current grace period
299 has extended for, or zero if there is no grace period currently
302 o "max" is the age in jiffies of the longest-duration grace period
320 o "jfq" is the number of jiffies remaining for this grace period
