I think I found reason... with PREEMPTION=y, in kernel/rcu/Kconfig: config TASKS_RCU def_bool PREEMPTION help This option enables a task-based RCU implementation that uses only voluntary context switch (not preemption!), idle, and user-mode execution as quiescent states. Not for manual selection. in kernel/rcu/Kconfig: config TASKS_RCU_GENERIC def_bool TASKS_RCU || TASKS_RUDE_RCU || TASKS_TRACE_RCU select SRCU help This option enables generic infrastructure code supporting task-based RCU implementations.
