Create a target for testing lkm_device with following steps:

  • Load module
  • Identify device major
  • Create device file in /device using previously identified major
  • Read a few messages from /device
  • Delete device file
  • Unload module

Probably integrate proc filesystem into the module to get access to the major number. Access to this major number could be done for example by: cat /proc/lkm/device instead of using somehow the Kernel Ring Buffer.
