Changelog:
----------
v1 -> v2:
- Wrap entire function signature in BPF_KFUNC macro instead of using
  __bpf_kfunc tag (Kumar)
- Update all kfunc definitions to use this macro.
- Update kfuncs.rst documentation to describe and illustrate the macro.
- Also clean up a few small parts of kfuncs.rst, e.g. some grammar, and
  in general making it a bit tighter.

David Vernet (3):
  bpf: Add BPF_KFUNC macro for defining kfuncs
  bpf: Document usage of the new BPF_KFUNC macro
  bpf: Use BPF_KFUNC macro at all kfunc definitions
