Subject: [PATCH V8 05/10] riscv: Enable ARCH_INLINE_READ*/WRITE*/SPIN*
Date: Sun, 24 Jul 2022 08:25:12 -0400	[thread overview]
Message-ID: <20220724122517.1019187-6-guoren@kernel.org> (raw)
In-Reply-To: <20220724122517.1019187-1-guoren@kernel.org>

From: Guo Ren <guoren@linux.alibaba.com>

Enable ARCH_INLINE_READ*/WRITE*/SPIN* when !PREEMPTION, it is copied
from arch/arm64. It could reduce procedure calls and improves
performance.
