Hi Robert, I love your patch! Yet something to improve: [auto build test ERROR on ras/edac-for-next] [also build test ERROR on linus/master v5.7-rc2 next-20200423] [cannot apply to bp/for-next linux/master] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Robert-Richter/EDAC-mc-ghes-Fixes-cleanup-and-reworks/20200424-042828 base: https://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git edac-for-next config: i386-allyesconfig (attached as .config) compiler: gcc-7 (Ubuntu 7.5.0-6ubuntu2) 7.5.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag as appropriate Reported-by: kbuild test robot All error/warnings (new ones prefixed by >>): In file included from arch/x86/include/asm/bug.h:83:0, from include/linux/bug.h:5, from include/linux/debug_locks.h:7, from include/linux/lockdep.h:44, from include/linux/spinlock_types.h:18, from include/linux/mutex.h:16, from include/linux/kernfs.h:12, from include/linux/sysfs.h:16, from include/linux/kobject.h:20, from include/linux/of.h:17, from include/linux/irqdomain.h:35, from include/linux/acpi.h:13, from include/acpi/apei.h:9, from include/acpi/ghes.h:5, from drivers/edac/ghes_edac.c:12: drivers/edac/ghes_edac.c: In function 'ghes_dimm_pool_create': >> include/linux/lockdep.h:409:52: error: invalid type argument of '->' (have 'struct mutex') #define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map) ^ include/asm-generic/bug.h:113:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^~~~~~~~~ include/linux/lockdep.h:435:27: note: in expansion of macro 'lockdep_is_held' WARN_ON(debug_locks && !lockdep_is_held(l)); \ ^~~~~~~~~~~~~~~ >> drivers/edac/ghes_edac.c:104:2: note: in expansion of macro 'lockdep_assert_held' lockdep_assert_held(ghes_reg_mutex); ^~~~~~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c: In function 'ghes_dimm_pool_destroy': >> include/linux/lockdep.h:409:52: error: invalid type argument of '->' (have 'struct mutex') #define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map) ^ include/asm-generic/bug.h:113:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^~~~~~~~~ include/linux/lockdep.h:435:27: note: in expansion of macro 'lockdep_is_held' WARN_ON(debug_locks && !lockdep_is_held(l)); \ ^~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c:118:2: note: in expansion of macro 'lockdep_assert_held' lockdep_assert_held(ghes_reg_mutex); ^~~~~~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c: In function 'ghes_dimm_alloc': >> include/linux/lockdep.h:409:52: error: invalid type argument of '->' (have 'struct mutex') #define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map) ^ include/asm-generic/bug.h:113:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^~~~~~~~~ include/linux/lockdep.h:435:27: note: in expansion of macro 'lockdep_is_held' WARN_ON(debug_locks && !lockdep_is_held(l)); \ ^~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c:127:2: note: in expansion of macro 'lockdep_assert_held' lockdep_assert_held(ghes_reg_mutex); ^~~~~~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c: In function 'ghes_dimm_release': >> include/linux/lockdep.h:409:52: error: invalid type argument of '->' (have 'struct mutex') #define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map) ^ include/asm-generic/bug.h:113:25: note: in definition of macro 'WARN_ON' int __ret_warn_on = !!(condition); \ ^~~~~~~~~ include/linux/lockdep.h:435:27: note: in expansion of macro 'lockdep_is_held' WARN_ON(debug_locks && !lockdep_is_held(l)); \ ^~~~~~~~~~~~~~~ drivers/edac/ghes_edac.c:144:2: note: in expansion of macro 'lockdep_assert_held' lockdep_assert_held(ghes_reg_mutex); ^~~~~~~~~~~~~~~~~~~ vim +/lockdep_assert_held +104 drivers/edac/ghes_edac.c 96 97 static int ghes_dimm_pool_create(int num_dimm) 98 { 99 struct ghes_dimm *ghes_dimm; 100 101 if (!num_dimm) 102 return 0; 103 > 104 lockdep_assert_held(ghes_reg_mutex); 105 106 dimms = kcalloc(num_dimm, sizeof(*dimms), GFP_KERNEL); 107 if (!dimms) 108 return -ENOMEM; 109 110 for (ghes_dimm = dimms; ghes_dimm < dimms + num_dimm; ghes_dimm++) 111 list_add(&ghes_dimm->entry, &ghes_dimm_pool); 112 113 return 0; 114 } 115 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
