Subject: [PATCH bpf-next 0/3] Improve raw tracepoint BTF types preservation

Fix issue with not preserving btf_trace_##call structs when compiled under
Clang. Additionally, capture raw tracepoint arguments in raw_tp_##call
structs, directly usable from BPF programs. Convert runqslower to use those
for proof of concept and to simplify code further.

Andrii Nakryiko (3):
  bpf: reliably preserve btf_trace_xxx types
  bpf: generate directly-usable raw_tp_##call structs for raw
    tracepoints
  tools/runqslower: simplify BPF code by using raw_tp_xxx structs
