[PATCH bpf-next v2 01/13] bpf: prefix cbpf internal helpers with bpf_
From: Daniel Borkmann <daniel@iogearbox.net>
Date: 2018-05-03 23:08:37
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [networking] (tcx & tc bpf, sock_addr), networking [general], the rest · Maintainers:

No change in functionality, just remove the '__' prefix and replace it with a 'bpf_' prefix instead. We later on add a couple of more helpers for cBPF and keeping the scheme with '__' is suboptimal there.
