| |
When building the kernel for the ARM architecture without setting CONFIG_AEABI, size of struct lov_user_md_v3 and struct lov_mds_md_v3 differs, due to different alignment requirements of OABI and EABI.
Marking the anonymous union within struct lov_user_md_v3 as '_packed' solves this issue. Otherwise we get the following error:
drivers/staging/lustre/lustre/lov/lov_pack.c:352:2: note: in expansion of macro ‘BUILD_BUG_ON’ BUILD_BUG_ON(sizeof(lum) != sizeof(struct lov_mds_md_v3));
