| |
dev_<level> macros use a lot of repetitive string space and arguments pr_<level> macros use repetitive unnecessary KERN_<level> strings
Eliminate the string prefixes and function arguments from all the macro uses and consolidate them in functions.
This patchset saves about 60K of text in an x86 defconfig.
This implementation adds the ability to use a struct va_format to emit a format string along with va_list arguments.
This %pV implementation should not be used without a wrapper that does printf argument verification like the dev_<level> functions.
Inspired a bit by Nick Andrew's patches and Linus' comments in December 2008 http://lkml.org/lkml/2008/12/6/15 http://lkml.org/lkml/2008/12/6/101
