2019-12-17debugfs: add 9p device interfaceOlivier Deprez
The 9p interface provides abstraction layers allowing the software that uses devices to be independent from the hardware. This patch provides a file system abstraction to link drivers to their devices and propose a common interface to expose driver operations to higher layers. This file system can be used to access and configure a device by doing read/write operations.
