Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) disable preemption in sender side of socket filters, from Alexei.

2) fix two potential deadlocks in syscall bpf lookup and prog_register,
   from Martin and Alexei.

3) fix BTF to allow typedef on func_proto, from Yonghong.

4) two bpftool fixes, from Jiri and Paolo.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
