其中"23807"表示宽限期kthread已经运行了23807个jiffies了。“"jiffies_till_next_fqs”表示宽限期kthread应该运行的频率,给出强制静止状态两次扫描之间的jiffies,在示例的case中,3远小于23807。最后打印rcu_node结构体的qsmask字段,一般是0。 267 If the relevant grace-period kthread has been unable to run ...

the "f" precedes the ->gp_flags command to the grace-period kthread, the "RCU_GP_WAIT_FQS" indicates that the kthread is waiting for a short timeout, the "state" precedes value of the task_struct ->state field, and the "cpu" indicates that the grace-period kthread last ran on ...
