Like the call trace shown above, rcu_node->lock will not be released until all the stalled cpus' backtrace finished in nmi_cpu_backtrace() or 10s timeout in nmi_trigger_cpumask_backtrace(), if there are pending IPI callbacks in the smp call_single_queue ahead of the ipi_cpu_backtrace callback contending for the same rcu_node->lock, deadlock will be inevitable. To avoid such problems, shorten the critical section that rcu_node->lock protects to avoid waiting for the backtrace process finish.

Like the call trace shown above, rcu_node->lock will not be released until all the stalled cpus' backtrace finished in nmi_cpu_backtrace() or 10s timeout in nmi_trigger_cpumask_backtrace(), if there are pending IPI callbacks in the smp call_single_queue ahead of the ipi_cpu_backtrace callback contending for the same rcu_node->lock, deadlock will be inevitable. To avoid such problems, shorten the critical section that rcu_node->lock protects to avoid waiting for the backtrace process finish.
