Exactly.
So next -mm release will not have this problem. Anyway I will check it

Thanks.

$ gunzip -c /proc/config.gz | egrep '(_RCU|HOTPLUG)'
CONFIG_HOTPLUG=y
# CONFIG_CLASSIC_RCU is not set
CONFIG_PREEMPT_RCU=y
# CONFIG_RCU_TRACE is not set
# CONFIG_HOTPLUG_CPU is not set
# CONFIG_HOTPLUG_PCI is not set
