Some block device integrity parameters are available in sysfs, but others are only accessible using the FS_IOC_GETLBMD_CAP ioctl. Add a metadata_size utility program to print out the logical block metadata size, PI offset, and PI size within the metadata. Example output: $ metadata_size /dev/ublkb0 metadata_size: 64 pi_offset: 56 pi_tuple_size: 8
