Hi,
This patchset has a few fixes to compiler warnings.
curious, which compiler/setup displayed the warnings?
It took me a few tries with different configs.
My most successful one was using gcc (14.1.1)
make -j24 ARCH=x86_64 W=12 2>&1 | tee warnings.log
I dug through the Logs (with grep)looking for BPF and
non macro expansion warnings.
Thanks!
I am studying the BPF subsystem and wish to bring more tangible contributions.
I would appreciate receiving suggestions on things to investigate.
I also documented a bit in my blog. I could help with docs here, too.

Thanks!
Changelog V1 -> V2:
- rebased all commits to updated for-next base
- removes new cases of the extra parameter for bpf_jit_binary_pack_finalize
- built and tested for ARM64
- sent the series for the test workflow:

Rafael Passos (3):
bpf: remove unused parameter in bpf_jit_binary_pack_finalize
bpf: remove unused parameter in __bpf_free_used_btfs
bpf: remove redeclaration of new_n in bpf_verifier_vlog
lgtm, nice cleanup
