Subject: [PATCH] qemu: blockjob: Handle 'pending' blockjob state only when we
|
|
need it
|
|
|
|
The 'pending' state needs to be handled by the blockjob code only when
|
|
the snapshot code requests a block-commit without auto-finalization.
|
|
|
|
If we always handle it we fail to properly remove the blockjob data for
|
|
the 'blockdev-create' job as that also transitions trhough 'pending' but
|
|
we'd never update it once it reaches 'concluded' as the code already
|
|
thinks that the job has finished and is no longer watching it.
|
|
|
|
Introduce a 'processPending' property into block job data and set it
|
|
only when we know that we need to process 'pending'.
|
|
|
