Subject: [PATCH 4/6] pvmove: check if participating LV is already exlcusively
|
|
|
2b52f6 |
active
|
|
|
2b52f6 |
|
|
|
2b52f6 |
When running pvmove, we need to decide whether pvmove has to be doing
|
|
|
2b52f6 |
exlusive or non-exclusive activations for LV.
|
|
|
2b52f6 |
|
|
|
2b52f6 |
Whenever LV that requires exlusive activation is present, it makes
|
|
|
2b52f6 |
pvmove exlusive. But when there is already activate i.e. linear LV
|
|
|
2b52f6 |
in exclusive mode it also needs to switch pvmove into 'exlusively
|
|
|
2b52f6 |
activating' pvmove.
|
|
|
2b52f6 |
|
|
|
