函数名称：init_kprobes

函数原型：static int __init init_kprobes(void)

返回类型：int

参数：无

2273  err等于0
2277  以i小于KPROBE_TABLE_SIZE循环
2278  INIT_HLIST_HEAD( & kprobe_table[i])
2279  INIT_HLIST_HEAD( & kretprobe_inst_table[i])
2280  raw_spin_lock_init( & (lock))
2283  err等于Lookup and populate the kprobe_blacklist.* Unlike the kretprobe blacklist, we'll need to determine* the range of addresses that belong to the said functions,* since a kprobe need not necessarily be at the beginning* of a function.
2285  如果err则
2286  打印错误信息("kprobes: failed to populate blacklist: %d\n", err)
2287  打印错误信息("Please take care of using kprobes.\n")
2290  如果kretprobe_blacklist_size则
2292  以name != NULL循环
2293  addr等于kprobe_lookup_name(name, 0)
2295  如果非addr则printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
2304  size of instruction slot 等于MAX_OPTINSN_SIZE
2307  NOTE: change this value only with kprobe_mutex held = true
2311  NOTE: change this value only with kprobe_mutex held = false
2313  err等于arch_init_kprobes()
2314  如果非err则err等于register_die_notifier( & kprobe_exceptions_nb)
2316  如果非err则err等于register_module_notifier( & kprobe_module_nb)
2319  kprobes_initialized等于err恒等于0
2321  如果非err则init_test_probes()
2323  返回:err
