Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add a riscv64 JIT for BPF, from Björn.
2) Implement BTF deduplication algorithm for libbpf which takes BTF type
information containing duplicate per-compilation unit information and
reduces it to an equivalent set of BTF types with no duplication and
without loss of information, from Andrii.
3) Offloaded and native BPF XDP programs can coexist today, enable also
offloaded and generic ones as well, from Jakub.
4) Expose various BTF related helper functions in libbpf as API which
are in particular helpful for JITed programs, from Yonghong.
5) Fix the recently added JMP32 code emission in s390x JIT, from Heiko.
6) Fix BPF kselftests' tcp_{server,client}.py to be able to run inside
a network namespace, also add a fix for libbpf to get libbpf_print()
working, from Stanislav.
7) Fixes for bpftool documentation, from Prashant.
8) Type cleanup in BPF kselftests' test_maps.c to silence a gcc8 warning,
from Breno.
