Subject: [PATCH] virStorageSourceParseBackingJSON: Move deflattening of json:
|
|
|
fbe740 |
URIs out of recursion

Originally virStorageSourceParseBackingJSON didn't recurse, but when
|
|
|
fbe740 |
the 'raw' driver support was added we need to parse it's information
|
|
|
fbe740 |
which contains nested 'file' object.
|
|
|
fbe740 |
|
|
|
fbe740 |
Since the deflattening helper recurses already there's no need to call
|
|
|
fbe740 |
it again. Move it one level up to the entry point.
