The patch titled Subject: slab: suppress warnings caused by expansion of for_each_memcg_cache if !MEMCG_KMEM has been removed from the -mm tree. Its filename was slab-link-memcg-caches-of-the-same-kind-into-a-list-fix.patch This patch was dropped because it was folded into slab-link-memcg-caches-of-the-same-kind-into-a-list.patch ------------------------------------------------------ From: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx> Subject: slab: suppress warnings caused by expansion of for_each_memcg_cache if !MEMCG_KMEM In file included from mm/slab_common.c:26:0: mm/slab_common.c: In function 'kmem_cache_destroy': >> mm/slab.h:259:30: warning: right-hand operand of comma expression has no effect [-Wunused-value] for (iter = NULL, tmp = NULL, (root); 0; ) ^ >> mm/slab_common.c:603:2: note: in expansion of macro 'for_each_memcg_cache_safe' for_each_memcg_cache_safe(c, c2, s) { ^ fixes: slab-link-memcg-caches-of-the-same-kind-into-a-list Signed-off-by: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/slab.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff -puN mm/slab.h~slab-link-memcg-caches-of-the-same-kind-into-a-list-fix mm/slab.h --- a/mm/slab.h~slab-link-memcg-caches-of-the-same-kind-into-a-list-fix +++ a/mm/slab.h @@ -254,9 +254,9 @@ extern void slab_init_memcg_params(struc #else /* !CONFIG_MEMCG_KMEM */ #define for_each_memcg_cache(iter, root) \ - for (iter = NULL, (root); 0; ) + for ((void)(iter), (void)(root); 0; ) #define for_each_memcg_cache_safe(iter, tmp, root) \ - for (iter = NULL, tmp = NULL, (root); 0; ) + for ((void)(iter), (void)(tmp), (void)(root); 0; ) static inline bool is_root_cache(struct kmem_cache *s) { _ Patches currently in -mm which might be from vdavydov@xxxxxxxxxxxxx are origin.patch list_lru-introduce-list_lru_shrink_countwalk.patch fs-consolidate-nrfree_cached_objects-args-in-shrink_control.patch vmscan-per-memory-cgroup-slab-shrinkers.patch memcg-rename-some-cache-id-related-variables.patch memcg-add-rwsem-to-synchronize-against-memcg_caches-arrays-relocation.patch list_lru-get-rid-of-active_nodes.patch list_lru-organize-all-list_lrus-to-list.patch list_lru-introduce-per-memcg-lists.patch fs-make-shrinker-memcg-aware.patch fs-shrinker-always-scan-at-least-one-object-of-each-type.patch slab-embed-memcg_cache_params-to-kmem_cache.patch slab-link-memcg-caches-of-the-same-kind-into-a-list.patch cgroup-release-css-id-after-css_free.patch slab-use-css-id-for-naming-per-memcg-caches.patch memcg-free-memcg_caches-slot-on-css-offline.patch list_lru-add-helpers-to-isolate-items.patch memcg-reparent-list_lrus-and-free-kmemcg_id-on-css-offline.patch slub-never-fail-to-shrink-cache.patch slub-never-fail-to-shrink-cache-init-discard-list-after-freeing-slabs.patch slub-fix-kmem_cache_shrink-return-value.patch slub-make-dead-caches-discard-free-slabs-immediately.patch memcg-cleanup-static-keys-decrement.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
