libparted: add support for implicit FBA DASD partitions
Fixed Block Access (FBA) DASDs are mainframe-specific disk devices
which are layed out as a sequence of 512-byte sectors. In contrast
to ECKD DASDs, these disks do not require formatting and resemble
the LBA layout of non-mainframe disks. Despite this resemblance,
the Linux kernel applies special handling during partition detection
for FBA DASDs, resulting in a single, immutable partition being
reported.
While actual FBA DASD hardware is no longer available, the z/VM
hypervisor can simulate FBA DASD disks, backed by either ECKD or
SCSI devices.
This patch adds support for recognizing FBA DASD partitions
to parted.
