[PATCH bpf 0/2] bpf fix for mixed tail calls and subprograms

[John Fastabend <john.fastabend@xxxxxxxxx>]

We recently tried to use mixed programs that have both tail calls and
subprograms, but it needs the attached fix. Also added a small test
addition that will cause the failure without the fix.

Thanks,
John
