函数名称：Prepare reljump right after instruction to boost

函数原型：static int prepare_boost(kprobe_opcode_t *buf, struct kprobe *p, struct insn *insn)

返回类型：int

参数：

类型参数名称
kprobe_opcode_t *buf
struct kprobe *p
struct insn *insn
400  len等于length
402  如果Returns non-zero if INSN is boostable.* RIP relative instructions are adjusted at copying time in 64 bits mode且MAX_INSN_SIZE减len大于等于RELATIVEJUMP_SIZE则
408  Insert a jump instruction at address 'from', which jumps to address 'to'.
410  len加等于RELATIVEJUMP_SIZE
411  stable = false: This instruction type is not boostable.* boostable = true: This instruction has been boosted: we have* added a relative jump after the instruction copy in insn,* so no single-step and fixup are needed (unless there's* a post_handler). = true
412  否则
413  stable = false: This instruction type is not boostable.* boostable = true: This instruction has been boosted: we have* added a relative jump after the instruction copy in insn,* so no single-step and fixup are needed (unless there's* a post_handler). = false
416  返回:len
