[parted-devel] [PATCH] libparted/dasd: add an exception for changing DASD-LDL partition table

[Wang Dong]

The partition table of DASD-LDL device with the dasd disk label
should not be changed according to its character in Linux.
When the user tries to modify the partition table, an exception
will be raised to inform user of this character.
