Organizing kernel messages

You would use a tool to check out the correct code.

The [git hash] would be the hash from most recent Linus tree. The [file number] would be the hash of the filename.

You could also assign a more permanent number by looking at the git hash for the patch which added the printk(). You could look the permentent number up on google or in your binder.

Actually the [git hash] would be stored in a file under /sys.
