Criteria for contributing to /samples directory?

Hi Community, My understanding is that /samples directory is where example or demonstrative code lives, but I was wondering if only the authors of kernel source code are allowed to contribute, or if the sample code has to be of certain complexity, etc. I have been experimenting with a proc filesystem driver and would love to share my learning with others who need some example code to look at. Would this be a good candidate to be in /samples? Thank you, Ann
