Wong Source kernel commit: 13877bc79d81354c53e91f3c86ac0f7bafe3ba7b Check this with every kernel and userspace build, so we can drop the nonsense in xfs/122. Roughly drafted with: sed -e 's/^offsetof/\tXFS_CHECK_OFFSET/g' \ -e 's/^sizeof/\tXFS_CHECK_STRUCT_SIZE/g' \ -e 's/ = \([0-9]*\)/,\t\t\t\1);/g' \ -e 's/xfs_sb_t/struct xfs_dsb/g' \ -e 's/),/,/g' \ -e 's/xfs_\([a-z0-9_]*\)_t,/struct xfs_\1,/g' \ < tests/xfs/122.out | sort and then manual fixups.
