当它们被访问时,内核通过devfs设备名称映射到合适的设备驱动程序,而不是通过主设备号。
When they are accessed, the kernel maps to the appropriate device driver by devfs device name, rather than by major number.
让特殊文件到内核驱动程序的映射成为可能的是主设备号,而不是真实的设备名称(它和非 devfs系统无关)。
The mapping from special file to kernel driver is made possible by the major number, not the actual device name, which is irrelevant to a non-devfs system.
