[parted-devel] [PATCH] disk.c: Update metadata after reading partition table

[Pascal Hambourg]

Make sure metadata and free space are updated after reading the
partition table. Else non-standard metadata length for an empty GPT
table may be incorrectly reported until a change is performed.

Fixes: #79720
