Hi all,

After merging the bpf-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

kernel/trace/bpf_trace.c:717:47: error: expected ')' before 'struct'
717 | BTF_ID_LIST_GLOBAL_SINGLE(btf_task_struct_ids, struct, task_struct)
| ^~~~~~~
| )
kernel/trace/bpf_trace.c: In function 'bpf_tracing_func_proto':
kernel/trace/bpf_trace.c:1051:11: error: 'bpf_get_current_task_btf_proto' undeclared (first use in this function); did you mean 'bpf_get_current_task_proto'?
1051 | return &bpf_get_current_task_btf_proto;
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| bpf_get_current_task_proto

Caused by commit

33c5cb36015a ("bpf: Consolidate task_struct BTF_ID declarations")

I have used the bpf-next tree from next-20210825 for today.
