From 14de1552a4e3fece78bb20314887e70888c9d448 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 11 Mar 2026 16:14:55 -0700 Subject: include/linux/local_lock_internal.h: Make this header file again compatible with sparse There are two versions of the __this_cpu_local_lock() definitions in include/linux/local_lock_internal.h: one version that relies on the Clang overloading functionality and another version that does not. Select the latter version when using sparse. This patch fixes the following errors reported by sparse: include/linux/local_lock_internal.h:331:40: sparse: sparse: multiple definitions for function '__this_cpu_local_lock' include/linux/local_lock_internal.h:325:37: sparse: the previous one is here Closes: https://lore.kernel.org/oe-kbuild-all/202603062334.wgI5htP0-lkp@intel.com/ Fixes: d3febf16dee2 ("locking/local_lock: Support Clang's context analysis") Reported-by: kernel test robot Signed-off-by: Bart Van Assche Signed-off-by: Peter Zijlstra (Intel) Reviewed-by: Marco Elver Link: https://patch.msgid.link/20260311231455.1961413-1-bvanassche@acm.org --- include/linux/local_lock_internal.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/linux') diff --git a/include/linux/local_lock_internal.h b/include/linux/local_lock_internal.h index eff711bf973f..234be7f12c15 100644 --- a/include/linux/local_lock_internal.h +++ b/include/linux/local_lock_internal.h @@ -315,7 +315,7 @@ do { \ #endif /* CONFIG_PREEMPT_RT */ -#if defined(WARN_CONTEXT_ANALYSIS) +#if defined(WARN_CONTEXT_ANALYSIS) && !defined(__CHECKER__) /* * Because the compiler only knows about the base per-CPU variable, use this * helper function to make the compiler think we lock/unlock the @base variable, -- cgit v1.3
