| * Socket state bits. |

| * Historically, this bits were all kept in the so_state field. For |
| * locking reasons, they are now in multiple fields, as they are |
| * locked differently. so_state maintains basic socket state protected |
| * by the socket lock. so_qstate holds information about the socket |
| * accept queues. Each socket buffer also has a state field holding |
| * information relevant to that socket buffer (can't send, rcv). Many |
| * fields will be read without locks to improve performance and avoid |
| * lock order issues. However, this approach must be used with caution. |
