Subject: bpf: prefix cbpf internal helpers with bpf_
X-Git-Tag: v4.18-rc1~114^2~304^2~3^2~12
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=b390134c2423c557cac844ee3b7cb52dc1cfab02;p=linux.git

bpf: prefix cbpf internal helpers with bpf_

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.
