Subject: [PATCH] locking/atomic: sh: Use generic_cmpxchg_local for arch_cmpxchg_local()
Date: Tue, 24 Oct 2023 23:52:54 +0900 [thread overview]
Message-ID: <169815917362.8695.13904684741526725648.stgit@devnote2> (raw)
From: Masami Hiramatsu (Google) <mhiramat@kernel.org>
Use generic_cmpxchg_local() for arch_cmpxchg_local() implementation
in SH architecture because it does not implement arch_cmpxchg_local().
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202310241310.Ir5uukOG-lkp@intel.com/
