I'd prefer something like that as well, and it is
a long-term goal I have, but not yet, no.
There are many files that use pr_<level> without pr_fmt.
Those need to be sorted out first, perhaps by adding a new
line to each of those files to "#define pr_fmt(fmt) fmt"
KBUILD_MODNAME is always #defined by the make system.
$ grep -rP --include=*.[ch] -lw "pr_(info|warn|warning|notice|debug|dbg|vdbg|crit|alert|err|emerg|cont)" * | \
while read file ; do \
grep -lwq pr_fmt $file ; \
echo "$?:$file"; \
done | \
cut -f1 -d":" | sort | uniq -c
Exit status 0 means a match for pr_fmt.
So there are ~1900 files that use pr_<level>
in the kernel tree, only 335 have pr_fmt.
This search does have some false negatives because
some files use an #include that does a #define pr_fmt.
Anyway, I'd like to sort it out eventually.
For now, I just add the #define pr_fmt, with
a long term goal of removing them all and using
a different mechanism to remove the duplicated
prefix string altogether from the formats and
save some text.
