For bpf_get_stack_proto_raw_tp, I chose ARG_PTR_TO_UNINIT_MEM to be consistent with its siblings: • bpf_get_stack_proto_tp (bpf_trace.c:1425) • bpf_get_stack_proto (stackmap.c:525) • bpf_get_stack_sleepable_proto (stackmap.c:541) All of these are wrappers around the same core function bpf_get_stack() / __bpf_get_stack(), passing the buffer with identical semantics, and all use ARG_PTR_TO_UNINIT_MEM.
