名称描述
__note_gp_changesUpdate CPU-local rcu_data state to record the beginnings and ends of* grace periods. The caller must hold the ->lock of the leaf rcu_node* structure corresponding to the current CPU, and must have irqs disabled.
rcu_gp_cleanupClean up after the old grace period.
rcu_report_qs_rdpRecord a quiescent state for the specified CPU to that CPU's rcu_data* structure. This must be called from the specified CPU.
rcu_do_batchInvoke any RCU callbacks that have made it to the end of their grace* period. Thottle as specified by rdp->blimit.
rcu_corePerform RCU core processing work for the current CPU.
__call_rcuHelper function for call_rcu() and friends. The cpu argument will* normally be -1, indicating "currently running CPU". It may specify* a CPU only if that CPU is a no-CBs CPU. Currently, only rcu_barrier()* is expected to specify a CPU.
rcu_pending
rcu_barrier_barrier - Wait until all in-flight call_rcu() callbacks complete
rcutree_prepare_cpuInvoked early in the CPU-online process, when pretty much all services* are available. The incoming CPU is not present.* Initializes a CPU's per-CPU RCU data. Note that only one online or* offline event can be happening at a given time
show_rcu_gp_kthreadsShow the state of the grace-period kthreads.
rcu_needs_cpuCheck to see if any future non-offloaded RCU-related work will need* to be done by the current CPU, even if none need be done immediately,* returning 1 if so
