If anyone has any objections, please let me know. ------------------ From: Xiongfeng Wang commit 321cb0308a9e76841394b4bbab6a1107cfedbae0 upstream. 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.
