[bpf-next,10/10] samples/bpf: change _kern suffix to .bpf with BPF test programs

Commit Message

Daniel T. Lee Jan. 15, 2023, 7:16 a.m. UTC

This commit changes the _kern suffix to .bpf with the BPF test programs.
With this modification, test programs will inherit the benefit of the
new CLANG-BPF compile target.
