Subject: [PATCH] qemu: blockjob: Don't base bitmap handling of active-layer
|
|
|
a41c76 |
block commit on QEMU_CAPS_BLOCKDEV_REOPEN
|
|
|
a41c76 |
|
|
|
a41c76 |
The handler finalizing the active layer block commit doesn't actually
|
|
|
a41c76 |
reopen the file for active layer block commit, so the comment and check
|
|
|
a41c76 |
are invalid.
