e1000设备驱动程序中e1000_tx_queue上的后缀“clone.44”

Question

e1000_tx_queue是e1000 linux设备驱动程序中的功能。当我将e1000的模块转储到汇编代码时，此函数被演示为e1000_tx_queue.clone.44。喜欢：

00000c10 <e1000_tx_queue.clone.44>:
 c10:   55                      push   %ebp
 c11:   89 e5                   mov    %esp,%ebp
 c13:   57                      push   %edi
 c14:   56                      push   %esi
 c15:   53                      push   %ebx
 c16:   83 ec 10                sub    $0x10,%esp
 c19:   e8 fc ff ff ff          call   c1a <e1000_tx_queue.clone.44+0xa>
        c1a: R_386_PC32 mcount

那么后缀“clone.44”在这种情况下是什么意思？这是由编译器添加的，用途是什么？ 感谢
