Kbuild: suppress packed-not-aligned warning for default setting only
gcc-8 reports many -Wpacked-not-aligned warnings. The below are some
examples.
./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
} __attribute__ ((packed));
./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
} __attribute__ ((packed));
./include/linux/ceph/msgr.h:67:1: warning: alignment 1 of 'struct
ceph_entity_addr' is less than 8 [-Wpacked-not-aligned]
} __attribute__ ((packed));
This patch suppresses this kind of warnings for default setting.
