What's the purpose of calculating this CRC in kernel space? Couldn't a userspace tool calculate it just as easily? Said tool could keep a database of messages that have changed so that they hash out to the same ID etc...

You want to calculate the CRC on the format string, not on the formatted string, and userspace never has access to the former at runtime.
