There's only one opinion, and >that's Linus's ;-) Fair enough :-) Regardless, I don't think we need to get too into the weeds about whether debugfs is a stable ABI or not here. Even if it is considered to be so, the ABI here would be the format and location of the printk index -- printk entries being added, changed, or removed are just backing data changes in the same way that adding or removing a map and that then being reflected in /proc/self/smaps isn't an ABI break either.
