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
