Subject: pull-request: bpf-next 2020-05-14
Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Merged tag 'perf-for-bpf-2020-05-06' from tip tree that includes CAP_PERFMON.
2) support for narrow loads in bpf_sock_addr progs and additional
helpers in cg-skb progs, from Andrey.
3) bpf benchmark runner, from Andrii.
4) arm and riscv JIT optimizations, from Luke.
5) bpf iterator infrastructure, from Yonghong.
Please consider pulling these changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git
Thanks a lot!
