返回类型：int

参数：

类型参数名称
struct trace_uprobe *new
476  new_inode等于d_real_inode - Return the real inode*@dentry: The dentry to query* If dentry is on a union/overlay, then return the underlying, real inode.* Otherwise return d_inode().
478  r_each_trace_uprobe - iterate over the trace_uprobe list*@pos: the struct trace_uprobe * for each entry*@dpos: the struct dyn_event * to use as a loop cursor(tmp, pos)
479  如果new_inode恒等于d_real_inode - Return the real inode*@dentry: The dentry to query* If dentry is on a union/overlay, then return the underlying, real inode.* Otherwise return d_inode().且offset恒等于offset且ref_ctr_offset不等于ref_ctr_offset则
