Subject: [PATCH net-next v2 0/3] BPF event output helper improvements

This set adds improvements to the BPF event output helper to
support non-linear data sampling, here specifically, for skb
context. For details please see individual patches. The set
is based against net-next tree.

v1 -> v2:
  - Integrated and adapted Peter's diff into patch 1, updated
    the remaining ones accordingly. Thanks Peter!

Thanks a lot!

Daniel Borkmann (3):
  perf, events: add non-linear data support for raw records
  bpf, perf: split bpf_perf_event_output
  bpf: avoid stack copy and use skb ctx for event output
