One possible long term goal is to stop adding
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
to source files to prefix modulename to logging output.
It might be useful to eventually have kernel.h
use a standard #define pr_fmt which includes KBUILD_MODNAME
instead of a blank or empty define.
Perhaps over time, the source modules that use pr_<level>
with prefixes can be converted to use pr_fmt.
If all modules are converted, that will allow the printk
routine to add module/filename/line/offset to the logging
lines using some function similar to dynamic_debug and
substantially reduct object string use by removing the
repeated prefixes.
This patchset does not get to that result. The patches
right now uses _more_ string space because all logging
messages have unshared prefixes but it may be a useful start.
The patchset strips prefixes from printks and adds pr_fmt to
arch/x86, crypto, kernel, and a few drivers.
It also converts printk(KERN_<level> to pr_<level> in a few files
that already had some pr_<level> uses.
The conversion also generally used long length format strings
in the place of multiple short strings to ease any grep/search.
