Does printk support escape sequences? The last time I tried
printk("\e[1;35m omg ponies \e[0m"); that did not went too successful.
It should handle \r correctly. If not that is easy to fix.
Escape codes are bad and should not be used - you may have a serial
console and not be on a Linux console
It's not printk(), or the console, that's the issue...
Consider logging to a file, which is quite common.
Dumping formatting characters in there is a bit evil.
Instead of using \r and overwrite, something like
Testing foo... ok
printk(KERN_INFO "Testing foo... ");
foo();
printk("ok\n");
... really is a lot better. We used to do that a lot more.
