参数：

类型参数名称
struct uprobe *uprobe
struct file *filp
821  mapping等于i_mapping
822  offs等于offset
823  insn等于insn
824  size等于insn的长度
825  err等于负EIO
828  循环
829  如果offs大于等于NOTE: in a 32bit arch with a preemptable kernel and* an UP compile the i_size_read/write must be atomic* with respect to the local cpu (unlike with preempt disabled),* but they don't need to be atomic with respect to other cpus like in* true SMP (so they 则退出

833  err等于__copy_insn(mapping, filp, insn, len, offs)
834  如果err则退出
837  insn加等于len
838  offs加等于len
839  size减等于len
840  当size循环
