Subject: [PATCH 3/4] DDF: fix possible mdmon crash when updating metadata.
|
||
|
|
|
||
|
|
Testing 'c' and then using 'vdc' assumes that the two are in sync,
|
||
|
|
but sometimes they aren't.
|
||
|
|
Testing 'vdc' is safer.
|
||
|
|
This avoids a crash in some cases when failing/removing/added devices
|
||
|
|
to a DDF.
