[PATCH 06/11] conf: Fix @tickpolicy member of _virDomainTimerDef struct
Michal Privoznik
mprivozn at redhat.com
Mon Jan 24 10:07:28 UTC 2022
The @tickpolicy member of the _virDomainTimerDef struct stores
values of the virDomainTimerTickpolicyType enum, or -1 for the
default value (when user provided no value in XML).
This is needlessly complicated. Introduce new value to the enum
which reflects the default state.
