Subject: [PATCH v3 5/5] arch,locking/atomic: xtensa: define arch_cmpxchg_local as __cmpxchg_local
Date: Tue, 21 Nov 2023 22:23:47 +0800 [thread overview]
Message-ID: <20231121142347.241356-6-wuqiang.matt@bytedance.com> (raw)
In-Reply-To: <20231121142347.241356-1-wuqiang.matt@bytedance.com>
The xtensa architecture already has __cmpxchg_local defined but not used.
The purpose of __cmpxchg_local() is solely for arch_cmpxchg_local(), just
as the definition of arch_cmpxchg_local() for other architectures like x86,
arm and powerpc.
