This issue can be reproduced by enabling\nCONFIG_NO_HZ_FULL and booting the kernel with argument \"nohz_full=\",\nand then giving the following commands at the shell prompt:\n\n # cd /sys/kernel/tracing/\n # echo 'p:mp1 __rcu_irq_enter_check_tick' >> kprobe_events\n # echo 1 > events/kprobes/enable\n\nThis commit therefore adds __rcu_irq_enter_check_tick() to the
