Commit ("[BPF] disable ReduceLoadWidth during SelectionDag phase") has been
merged in trunk 11.0. The commit disabled ReduceLoadWidth during SelectionDAG
phase to avoid generating kernel verifier unfriendly code. The unfriendly code
is more likely to be generated when CO-RE (compiler once, run everywhere) is
enabled.
