Subject: [PATCH bpf-next v5 0/2] bpf: Allow bpf_skb_event_output for more prog types

Software event output is only enabled by a few prog types right now (TC,
LWT out, XDP, sockops). Many other skb based prog types need
bpf_skb_event_output to produce software event.

More prog types are enabled to access bpf_skb_event_output in this
patch.

v2 changes:
Reformating log message.

v3 changes:
