Hi! Just a small idea, what about including example userspace application which would use this new API? I think such application can be useful for documentation purpose to see how this new API should be used. And in review process other people can point if there would be some problems with usage. I do not know if it is requirement or not for introducing new kernel API, but still example code is very useful for developers when they would start to use this new API and correctly. -- Pali Rohár pali.rohar@xxxxxxxxx
