函数名称：Check given address is on the page of kprobe instruction slots.* This will be used for checking whether the address on a stack* is on a text area or not.

函数原型：bool __is_insn_slot_addr(struct kprobe_insn_cache *c, unsigned long addr)

返回类型：bool

参数：

类型参数名称
struct kprobe_insn_cache *c
unsigned longaddr
278  bool ret = false
280  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
282  如果addr大于等于Page of instruction slots 且addr小于Page of instruction slots 加PAGE_SIZE则
284  ret = true
285  退出
288  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
290  返回:ret
