Subject: ebpf: include perf_event only where really needed
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0cdf5640e4f6940bdbbefee4bb0adb7dffb185ec;p=openwrt%2Fstaging%2Fblogic.git

ebpf: include perf_event only where really needed

Commit ea317b267e9d ("bpf: Add new bpf map type to store the pointer
to struct perf_event") added perf_event.h to the main eBPF header, so
it gets included for all users. perf_event.h is actually only needed
from array map side, so lets sanitize this a bit.
