Subject: pull-request: bpf-next 2019-04-22
Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) allow stack/queue helpers from more bpf program types, from Alban.
2) allow parallel verification of root bpf programs, from Alexei.
3) introduce bpf sysctl hook for trusted root cases, from Andrey.
4) recognize var/datasec in btf deduplication, from Andrii.
5) cpumap performance optimizations, from Jesper.
6) verifier prep for alu32 optimization, from Jiong.
7) libbpf xsk cleanup, from Magnus.
8) other various fixes and cleanups.
Please consider pulling these changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git
Thanks a lot!
