rcu_segcblist

函数名称：Is the specified rcu_segcblist structure empty?* But careful! The fact that the ->head field is NULL does not* necessarily imply that there are no callbacks associated with* this structure. When callbacks are being invoked, they are* removed as a group

函数原型：static inline bool rcu_segcblist_empty(struct rcu_segcblist *rsclp)

返回类型：bool

**调用者**
名称	描述
srcu_torture_stats_print
rcu_do_batch	Invoke any RCU callbacks that have made it to the end of their grace* period. Thottle as specified by rdp->blimit.
__call_rcu	Helper 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.
rcutree_prepare_cpu	Invoked 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
rcu_segcblist_disable	Disable the specified rcu_segcblist structure, so that callbacks can* no longer be posted to it. This structure must be empty.
rcu_needs_cpu	Check 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
