函数名称：We have to fix things up as follows:* Typically, the new ip is relative to the copied instruction

函数原型：static int default_post_xol_op(struct arch_uprobe *auprobe, struct pt_regs *regs)

返回类型：int

参数：

类型参数名称
struct arch_uprobe *auprobe
struct pt_regs *regs
555  utask等于utask
557  riprel_post_xol(auprobe, regs)
558  如果fixups按位与Adjust IP back to vicinity of actual insn 则
559  correction等于vaddr减xol_vaddr
560  Return frame for iretq 加等于correction
561  否则如果fixups按位与Adjust the return address of a call insn 则
562  sp加等于sizeof_long(regs)
563  如果emulate_push_stack(regs, vaddr + ilen)则返回:负ERESTART
567  如果fixups按位与Instruction will modify TF, don't change it 则saved_tf = true
570  返回:0
