Subject: [PATCH 08/12] VMDK: move 'static' cid_update flag to bs field
|
||
|
|
|
||
|
|
Cid_update is the flag for updating CID on first write after opening the
|
||
|
|
image. This should be per image open rather than per program life cycle,
|
||
|
|
so change it from static var of vmdk_write to a field in BDRVVmdkState.
