Making EPERM friendlier

I'm glad that kernel developers are taking this seriously. It's gotten to the point that the first response to a "permission denied" error is to start chmod'ing things to 777, disabling the LSM, running things as root, moving important paths to world-writable directories, or other extreme measures simply because there are too many things to check, and if you check them all carefully you might not disable the message (and therefore not find the cause).

People arguing about the security implications here should be arguing about how to secure their logs, not how to sanitize them.
