The patch is still under discussion. AFAIK, Rasmus is working on v4.
The main points are:

  + Rename the ambiguous "errcode" to "errname".

  + Introduce "%pe" instead of enhancing plain %p. First, the plain %p
    has become almost useless (hashing) on purpose (avoid leaking
    addresses). Second, we need something that will be explicitly
    used to print error codes.

  + Plus there are few more cosmetic issues.

I planed to take the patch via printk.git once ready.

Best Regards,
Petr
