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!
