[bpf-next PATCH 2/2] selftests/bpf: Enable stack argument tests for riscv
From: Feng Jiang
Date: Wed Aug 12 2026 - 02:20:13 EST
Add __TARGET_ARCH_riscv to the architecture guard in all stack
argument selftests so the real test cases are compiled for RISC-V.
Keep the __BPF_FEATURE_STACK_ARGUMENT gate, defined by clang with
BPF stack argument support [1].
