True, I prepared a fixed patch with libdisk removed. Also, it looks to me like ft.sectoralign in xfs_mkfs.c is not used anymore:
if (ft.sectoralign) {
/*
* Older Linux software RAID versions want the sector size
* to match the block size to avoid switching I/O sizes.
* For the legacy libdisk case we thus set the sector size to
* match the block size. For systems using libblkid we assume
* that the kernel is recent enough to not require this and
* ft.sectoralign will never be set.
*/
sectorsize = blocksize;
}
So I removed it too.
