Thanks for the fixes! I left a few comments in a few patches, please
address those. But also
please provide a commit message, even if a single line one. Kernel
style dictates that the commit message shouldn't be empty.

And I think none of these fixes are critical enough to go to bpf tree,
please target bpf-next for next revision. Thanks.

Will do, thanks

Ok, will target to bpf-next branch, targeting bpf tree just because
Documentation/bpf/bpf_devel_QA.rst says bpf-next is for features
