Subject: bpf: mark bpf_event_notify and bpf_event_init as static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=390e99cfdda1334f45c718cc02cd26eb3135f233;p=linux.git

bpf: mark bpf_event_notify and bpf_event_init as static

Both of them are not declared in the headers and not used outside
of bpf_trace.c file.

Fixes: a38d1107f937c ("bpf: support raw tracepoints in modules")
