tcp - inode 列 (proc/net/tcp(6)) 中的值是什么意思？

Question

这是一段 /proc/net/tcp 文件：

sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode

6：1904A8C0：AC35 9603020A：1ED0 01 00000000：00000000 00 00：0000000000000000000000000055550555 0 8506 2 C1624900 129 0 10 10 -1
7：1904A8C0：E8C4 13A11C1F：E8C4 13A11C1F：0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000099性使00000000.00.州000000000000000000000000000000000000000000000000000000000000000来

谁能解释一下 inode 列中的值是什么意思？我对两种情况感兴趣。

8506 2 c1624900 129 0 0 10 -1

0 3 d6267780

我只知道第一个值是 inode 号（唯一文件号）。
