From 4ed8773b5055363f1666345dd5ae5af12c7c6268 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Mon, 29 Jan 2018 16:12:30 +0100 Subject: [PATCH] KVM: s390: fix fallthrough annotation A case statement in kvm_s390_shadow_tables uses fallthrough annotations which are not recognized by gcc because they are hidden within a block. Move these annotations out of the block to fix (W=1) warnings like below: arch/s390/kvm/gaccess.c: In function 'kvm_s390_shadow_tables': arch/s390/kvm/gaccess.c:1029:26: warning: this statement may fall through [-Wimplicit-fallthrough=] case ASCE_TYPE_REGION1: { ^ Signed-off-by: Sebastian Ott Reviewed-by: Cornelia Huck Reviewed-by: David Hildenbrand Signed-off-by: Christian Borntraeger --- arch/s390/kvm/gaccess.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) diff --git a/arch/s390/kvm/gaccess.c b/arch/s390/kvm/gaccess.c index c24bfa72baf7..8e2b8647ee12 100644 --- a/arch/s390/kvm/gaccess.c +++ b/arch/s390/kvm/gaccess.c @@ -1050,8 +1050,7 @@ shadow_r2t: rc = gmap_shadow_r2t(sg, saddr, rfte.val, *fake); if (rc) return rc; - /* fallthrough */ - } + } /* fallthrough */ case ASCE_TYPE_REGION2: { union region2_table_entry rste; @@ -1077,8 +1076,7 @@ shadow_r3t: rc = gmap_shadow_r3t(sg, saddr, rste.val, *fake); if (rc) return rc; - /* fallthrough */ - } + } /* fallthrough */ case ASCE_TYPE_REGION3: { union region3_table_entry rtte; @@ -1113,8 +1111,7 @@ shadow_sgt: rc = gmap_shadow_sgt(sg, saddr, rtte.val, *fake); if (rc) return rc; - /* fallthrough */ - } + } /* fallthrough */ case ASCE_TYPE_SEGMENT: { union segment_table_entry ste; -- 2.25.1
