Subject: [PATCH v4 3/4] selftests/bpf: Enable kptr_xchg_inline test on LoongArch
Date: Wed, 29 Jul 2026 10:28:36 +0800 [thread overview]
Message-ID: <20260729022837.355549-4-chenguang.zhao@linux.dev> (raw)
In-Reply-To: <20260729022837.355549-1-chenguang.zhao@linux.dev>
From: Chenguang Zhao <zhaochenguang@kylinos.cn>
Run the kptr_xchg_inline functional test on LoongArch64 now that the bpf
JIT can inline bpf_kptr_xchg() with correct memory ordering.
Signed-off-by: Chenguang Zhao <zhaochenguang@kylinos.cn>
