When block size is larger than inode cluster size, the call to XFS_B_TO_FSBT(mp, mp->m_inode_cluster_size) returns 0. Also, mkfs.xfs would have set xfs_sb->sb_inoalignmt to 0. Hence in xfs_set_inoalignment(), xfs_mount->m_inoalign_mask gets initialized to -1 instead of 0. However, xfs_mount->m_sinoalign would get correctly intialized to 0 because for every positive value of xfs_mount->m_dalign, the condition "!(mp->m_dalign & mp->m_inoalign_mask)" would evaluate to false. Also, xfs_imap() worked fine even with xfs_mount->m_inoalign_mask having -1 as the value because blks_per_cluster variable would have the value 1 and hence we would never have a need to use xfs_mount->m_inoalign_mask to compute the inode chunk's agbno and offset within the chunk.
