H A Dscsi_eh.rst25 [1-2] scmd（SCSI 命令）是如何完成的？
26 [1-2-1] 通过scsi_done完成scmd
27 [1-2-2] 通过超时机制完成scmd
32 [2-1-2] scmd在错误处理流程中的传递路径
46 每个SCSI命令都由struct scsi_cmnd（简称scmd）结构体
47 表示。scmd包含两个list_head类型的链表节点：scmd->list
48 与scmd->eh_entry。其中scmd->list是用于空闲链表或设备
49 专属的scmd分配链表，与错误处理讨论关联不大。而
50 scmd->eh_entry则是专用于命令完成和错误处理链表，除非
51 特别说明，本文讨论中所有scmd的链表操作均通过
