Subject: [PATCH v2 bpf-next 0/2] Make bpf_endian.h compatible with vmlinux.h

Change libbpf's bpf_endian.h header to be compatible when used with system
headers and when using just vmlinux.h. This is a frequent request for users
writing BPF CO-RE applications. Do this by re-implementing byte swap
compile-time macros. Also add simple tests validating correct results both for
byte-swapping built-ins and macros.

Andrii Nakryiko (2):
  libbpf: make bpf_endian co-exist with vmlinux.h
  selftests/bpf: add byte swapping selftest
