So extend the alignment to 64 bytes # to cover more similar cases. # # [1].https://lore.kernel.org/lkml/20210427090013.GG32408@xsang-OptiPlex-9020/ # [2].https://lore.kernel.org/lkml/20210420030837.GB31773@xsang-OptiPlex-9020/ # Signed-off-by: Feng Tang <feng.tang@intel.com> # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 9324130f65f68433372472702ee12969340ce1c3 # < make -s -j 24 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- defconfig # < make -s -j 24 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 24 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/s390-linux/bin/s390-linux- /kisskb/src/net/sched/sch_frag.c: In function 'sch_fragment': /kisskb/src/net/sched/sch_frag.c:93:10: warning: missing braces around initializer [-Wmissing-braces] struct rtable sch_frag_rt = { 0 }; ^ /kisskb/src/net/sched/sch_frag.c:93:10: warning: (near initialization for 'sch_frag_rt.dst') [-Wmissing-braces] /kisskb/src/fs/btrfs/tree-checker.c: In function 'check_root_item': /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: missing braces around initializer [-Wmissing-braces] struct btrfs_root_item ri = { 0 }; ^ /kisskb/src/fs/btrfs/tree-checker.c:1071:9: warning: (near initialization for 'ri.inode') [-Wmissing-braces] /kisskb/src/net/openvswitch/actions.c: In function 'ovs_fragment': /kisskb/src/net/openvswitch/actions.c:830:10: warning: missing braces around initializer [-Wmissing-braces] struct rtable ovs_rt = { 0 }; ^ /kisskb/src/net/openvswitch/actions.c:830:10: warning: (near initialization for 'ovs_rt.dst') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/kbuild_s390-defconfig_s390x-gcc4.9 # Build took: 0:05:21.894605
