[parted-devel] [PATCH] dasd: avoid usage of uninitialized data

[Petr Uzel]

In ped_partition_new(), disk_specific data of PedPartition
structure is allocated (via dasd_partition_new()). This
data is later used uninitialized in dasd_partition_set_system().

* libparted/labels/vtoc.c (dasd_partition_new):
Zero out allocated disk_specific data.
