pr_<level> logging uses allow a prefix to be specified with a
specific #define pr_fmt
The default of pr_fmt in printk.h is #define pr_fmt(fmt) fmt
so no prefixing of logging output is generically done.
There are several output logging uses like dump_stack() that are
unprefixed and should remain unprefixed.
This patch series attempts to convert the default #define of pr_fmt to
KBUILD_MODNAME ": " fmt and as well update the various bits of the kernel
that should _not_ be prefixed by adding #define pr_fmt(fmt) fmt to those
compilation units that do not want output message prefixing.
There are about 1200 uses of #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
that could be removed if the default is changed.
A script that does this removal (and removes any blank lines that follow)
for the linux-kernel tree is included below:
$ git grep -P --name-only "define\s+pr_fmt\b" | \
grep -v include/linux/printk.h | \
xargs perl -i -e 'local $/; while (<>) {s/(\n)*[ \t]*#[ \t]*define[ \t]+pr_fmt[ \t]*\([ \t]*(\w+)[ \t]*\)[ \t]*KBUILD_MODNAME[ \t]*\": \"[ \t]*\2[ \t]*\n\s*/\1\n/; s/^\n//; print;}'
This script should be run after this patch series is applied.
