[libvirt] [PATCHv2 3/8] remote: consolidate typed parameter handling

* src/remote/remote_protocol.x (remote_typed_param_value) (remote_typed_param): New types. (remote_sched_param_value, remote_sched_param) (remote_blkio_param_value, remote_blkio_param) (remote_memory_param_value, remote_memory_param): Delete. (remote_domain_get_scheduler_parameters_ret) (remote_domain_set_scheduler_parameters_args) (remote_domain_set_scheduler_parameters_flags_args) (remote_domain_set_blkio_parameters_args) (remote_domain_get_blkio_parameters_ret) (remote_domain_set_memory_parameters_args) (remote_domain_get_memory_parameters_ret): Update clients. * src/remote_protocol-structs: Likewise. * src/remote/remote_driver.c (remoteSerializeTypedParameters) (remoteDeserializeTypedParameters): New functions. (remoteDomainSetMemoryParameters) (remoteDomainGetMemoryParameters, remoteDomainSetBlkioParameters) (remoteDomainGetBlkioParameters) (remoteDomainGetSchedulerParameters) (remoteDomainSetSchedulerParameters) (remoteDomainSetSchedulerParametersFlags): Update clients. * daemon/remote.c (remoteSerializeTypedParameters) (remoteDeserializeTypedParameters): New functions. (remoteDispatchDomainGetSchedulerParameters) (remoteDispatchDomainSetSchedulerParameters) (remoteDispatchDomainSetSchedulerParametersFlags) (remoteDispatchDomainSetMemoryParameters) (remoteDispatchDomainGetMemoryParameters) (remoteDispatchDomainSetBlkioParameters) (remoteDispatchDomainGetBlkioParameters): Update clients. --- daemon/remote.c | 502 ++++++++++++++--------------------------- src/remote/remote_driver.c | 467 ++++++++++++++------------------------- src/remote/remote_protocol.x | 74 ++----- src/remote_protocol-structs | 52 +---- 4 files changed, 365 insertions(+), 730 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index 90572c2..75abddd 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -495,6 +495,143 @@ cleanup: return rv;
