* 32bit struct xfs_fsop_bulkreq has different size and layout of members, no matter the alignment. Move the code out of the #else branch (why was it there in the first place?). Define _32 variants of the ioctl constants. * 32bit struct xfs_bstat is different because of time_t and on i386 because of different padding. Make xfs_bulkstat_one() accept a custom "output formatter" in the private_data argument which takes care of the xfs_bulkstat_one_compat() that takes care of the different layout in the compat case. * i386 struct xfs_inogrp has different padding. Add a similar "output formatter" mecanism to xfs_inumbers().
