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 <lkp@intel.com> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Marco Elver <elver@google.com> Link: https://patch.msgid.link/20260311231455.1961413-1-bvanassche@acm.org
