151  如果Is this kprobe disabled ? 则返回
154  禁止抢占()
155  如果kprobe_running() will just return the current_kprobe on this CPU 则
156  kprobes_inc_nmissed_count( & kp)
157  否则
158  kcb等于get_kprobe_ctlblk()
160  cs等于Segment selector values corresponding to the above entries:
162  cs或等于get_kernel_rpl()
163  gs等于0
165  ip等于 location of the probe point 加INT3_SIZE
166  orig_ax等于0UL的反
168  __this_cpu_write(current_kprobe, & kp)
169  kprobe_status等于kprobe_status settings
170  opt_pre_handler( & kp, regs)
