Subject: [PATCH v3 1/3] KVM: riscv: selftests: Use the existing RISCV_FENCE macro in `rseq-riscv.h`
Date: Mon, 1 Sep 2025 15:35:49 +0800 [thread overview]
Message-ID: <85e5e51757c9289ca463fbc4ba6d22f9c9db791b.1756710918.git.dayss1224@gmail.com> (raw)
In-Reply-To: <cover.1756710918.git.dayss1224@gmail.com>
From: Quan Zhou <zhouquan@iscas.ac.cn>
To avoid redefinition issues with RISCV_FENCE,
directly reference the existing macro in `rseq-riscv.h`.
