I have no objection to text form interface.  I said printk is not a tool
oriented interface not because it is a text form interface but some
other issues.  For example, messages from different CPU/context may be
interleaved; all kinds information mixed together, without overall
format or meta-data, etc.

Linux kernel uses binary format interfaces too.
