 Description   

Periodically when debugging a lustre issue on newer kernels developers run into the default behavior of %p to hash the address. While this safe default hinders bad actors it also frustrates developers.

Lets start by defaulting %p to %pK and slowly decorating pointers with the available pointer decorators. See: https://docs.kernel.org/core-api/printk-formats.html
