It is straightforward to update the header file for the esoteric, voluminous debugging. If you are missing critical hardware or software errors, that is an argument that those error messages should be outside of DEBUG/VDEBUG, shipped with every kernel.

We may need to do this in several header files, if we don't have common header for two source files. Also, having this as config option would be more helpful for people who don't have much knowhow of "how dev_dbg and dev_vdbg works". > If you are missing critical hardware or software errors, that is an > argument that those error messages should be outside of DEBUG/VDEBUG, > shipped with every kernel. That's not my case. I wanted to print debug info.
