Merge branch 'bpf: Small nf_conn cleanups'
Daniel Xu says:
====================
This patchset cleans up a few small things:
* Delete unused stub
* Rename variable to be more descriptive
* Fix some `extern` declaration warnings
Past discussion:
- v2: https://lore.kernel.org/bpf/cover.1663616584.git.dxu@dxuuu.xyz/
Changes since v2:
- Remove unused #include's
- Move #include <linux/filter.h> to .c
====================
