[PATCH 07/18] util: storage: Rename "path" to "relPath" in virStorageFileMetadata

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To allow future change of virStorageFileMetadata to virStorageSource we
need to store a full path in the "path" variable as rest of the code
expects it to be a full path. Rename the "path" field to "relPath" to
keep tracking the info but allowing a real "path" field.
