I have a collection of hacked-together tools that I use to test most of the various interfaces of printk. I would need to clean them up if they should be used for any kind of automated regression testing.
And where should I make such things available? I could put them in a repo in the Linutronix github account (like I did for the ringbuffer stress testing tool). (??)
