Hi David,

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

We've added 11 non-merge commits during the last 2 day(s) which contain
a total of 24 files changed, 216 insertions(+), 135 deletions(-).

The main changes are:

1) Fix UAPI for BPF map iterator before it gets frozen to allow for more
   extensions/customization in future, from Yonghong Song.

2) Fix selftests build to undo verbose build output, from Andrii Nakryiko.

3) Fix inlining compilation error on bpf_do_trace_printk() due to variable
   argument lists, from Stanislav Fomichev.

4) Fix an uninitialized pointer warning at btf__parse_raw() in libbpf,
   from Daniel T. Lee.

5) Fix several compilation warnings in selftests with regards to ignoring
   return value, from Jianlin Lv.

6) Fix interruptions by switching off timeout for BPF tests, from Jiri Benc.
