Subject: Re: linux-next: Tree for Mar 5 (bpf_trace)

This fails as we added bpf_test_run_tracing in net/bpf/test_run.c
which gets built only CONFIG_NET is enabled. Which, this particular
config, disables.

Alexei, if it's okay with you. I can send a patch that separates the
tracing test code into kernel/bpf/test_run_trace.c which depends
only on CONFIG_BPF_SYSCALL.
