Subject: [PATCH bpf-next v2 01/13] bpf: prefix cbpf internal helpers with bpf_
Date: Fri,  4 May 2018 01:08:12 +0200	[thread overview]
Message-ID: <20180503230824.3462-2-daniel@iogearbox.net> (raw)
In-Reply-To: <20180503230824.3462-1-daniel@iogearbox.net>

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.
