Re: [libvirt] [PATCH 2/2] maint: enforce use of _LAST marker

When converting a linear enum to a string, we have checks in place in the VIR_ENUM_IMPL macro to ensure that there is one string for every value, which lets us quickly flag if a user added a value but forgot to add a counterpart string. However, this only works if we use the _LAST marker. * cfg.mk (sc_require_enum_last_marker): New syntax check. * src/conf/domain_conf.h (virDomainSnapshotState): Add new marker. * src/conf/domain_conf.c (virDomainSnapshotState): Fix offender. * src/qemu/qemu_monitor_json.c (qemuMonitorWatchdogAction) (qemuMonitorIOErrorAction, qemuMonitorGraphicsAddressFamily): Likewise. * src/util/virtypedparam.c (virTypedParameter): Likewise.
