Re: [libvirt] [PATCHv2 5/6] util: use new virTypedParameter helpers

Reusing common code makes things smaller; it also buys us some additional safety, such as now rejecting duplicate parameters during a set operation. * src/qemu/qemu_driver.c (qemuDomainSetBlkioParameters) (qemuDomainSetMemoryParameters, qemuDomainSetNumaParameters) (qemuSetSchedulerParametersFlags) (qemuDomainSetInterfaceParameters, qemuDomainSetBlockIoTune) (qemuDomainGetBlkioParameters, qemuDomainGetMemoryParameters) (qemuDomainGetNumaParameters, qemuGetSchedulerParametersFlags) (qemuDomainBlockStatsFlags, qemuDomainGetInterfaceParameters) (qemuDomainGetBlockIoTune): Use new helpers. * src/esx/esx_driver.c (esxDomainSetSchedulerParametersFlags) (esxDomainSetMemoryParameters) (esxDomainGetSchedulerParametersFlags) (esxDomainGetMemoryParameters): Likewise. * src/libxl/libxl_driver.c (libxlDomainSetSchedulerParametersFlags) (libxlDomainGetSchedulerParametersFlags): Likewise. * src/lxc/lxc_driver.c (lxcDomainSetMemoryParameters) (lxcSetSchedulerParametersFlags, lxcDomainSetBlkioParameters) (lxcDomainGetMemoryParameters, lxcGetSchedulerParametersFlags) (lxcDomainGetBlkioParameters): Likewise. * src/test/test_driver.c (testDomainSetSchedulerParamsFlags) (testDomainGetSchedulerParamsFlags): Likewise. * src/xen/xen_hypervisor.c (xenHypervisorSetSchedulerParameters) (xenHypervisorGetSchedulerParameters): Likewise. --- src/esx/esx_driver.c | 81 +++--- src/libxl/libxl_driver.c | 44 +--- src/lxc/lxc_driver.c | 218 +++++----------- src/qemu/qemu_driver.c | 656 ++++++++++++++-------------------------------- src/test/test_driver.c | 27 +-- src/xen/xen_hypervisor.c | 51 ++-- 6 files changed, 350 insertions(+), 727 deletions(-)
