Hi Shuah,
I'm working on a kernel patch set where I need to write JSON.
After looking around a bit, I found this C-module with multiple
redundant copies scattered around tools/:
❯ find -name json_writer.[ch]
./tools/testing/selftests/bpf/json_writer.h
./tools/testing/selftests/bpf/json_writer.c
./tools/bpf/bpftool/json_writer.h
./tools/bpf/bpftool/json_writer.c
./tools/net/ynl/ynltool/json_writer.h
./tools/net/ynl/ynltool/json_writer.c
My (arbitrary) guess is that one in bpftool is the main copy.
Ssince the module is self-contained, I'm dilating towards doing this:
$(OUTPUT)/kcontainerd: kcontainerd.c ../../../bpf/bpftool/json_writer.c \
../../../bpf/bpftool/json_writer.h
$(CC) $(CFLAGS) $< ../../../bpf/bpftool/json_writer.c -o $@
(and in kcontainerd.c #include "../../../bpf/bpftool/json_writer.h")
I'm just sanity checking this given that json_writer is utilized with
a different pattern :-)
BR, Jarkko
