Subject: [PATCH bpf-next v4 25/25] selftests/bpf: Enable stack argument tests for arm64
Date: Tue, 12 May 2026 21:52:04 -0700 [thread overview]
Message-ID: <20260513045204.2403441-1-yonghong.song@linux.dev> (raw)
In-Reply-To: <20260513044949.2382019-1-yonghong.song@linux.dev>
From: Puranjay Mohan <puranjay@kernel.org>
Now that arm64 supports stack arguments, enable the existing stack_arg,
stack_arg_kfunc and verifier_stack_arg tests for __TARGET_ARCH_arm64.
