Subject: [PATCH V9 10/15] riscv: Enable ARCH_INLINE_READ*/WRITE*/SPIN*
Date: Mon,  8 Aug 2022 03:13:13 -0400	[thread overview]
Message-ID: <20220808071318.3335746-11-guoren@kernel.org> (raw)
In-Reply-To: <20220808071318.3335746-1-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.
