Subject: [PATCH 105/106] parted: fix wrong error label jump in mkpart
|
|
|
|
When the user makes a new partition, if parted fails to add the
|
|
partition to disk, it jumps to wrong error label. In this
|
|
situation, this new partition actually is not a node in disk
|
|
data structure. But in the wrong error label, it pretends this
|
|
is a node and removes it as a list node, leading to other
|
|
partition in this disk deleted. This might lead to a memory leak.
|
|
Because if there are other partitions, it just removes them from
|
|
list without releasing the resource. And this also leads to different
|
|
disk information between memory and device. This is confusing.
|
|
|
|
But when the new partition is added to disk successfully and if
|
|
any operations followed fail, this partition should be removed from
|
|
disk and destroyed.
