Note: This article is currently only a draft and is a part of a series of articles I'm going to publish the next few months - if you want to contribute to it, please feel free to. However it would be nice if you could coordinate your efforts with me
What this article will be about - ideas
- printk format
- Debug/log levels - dmesg -n /proc/sys/kernel/printk
- printk_ratelimited
- dynamic debug, pr_debug and dev_dbg
- pr_warn and family - see printk.h for details
- Examples - maybe use example module.
