[PATCH 13/13] qemu: snapshot: Remove unnecessary 'do_transaction' logic in qemuDomainSnapshotCreateDiskActive

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that we never get to the actual snapshot code if there's nothing to
do we can remove the variable and surrounding logic.
