A future patch will allow recursion into backing chains when collecting block stats. This patch should not change behavior, but merely moves out the common code that will be reused once recursion is enabled, and adds the parameter that will turn on recursion. * src/qemu/qemu_monitor.h (qemuMonitorGetAllBlockStatsInfo) (qemuMonitorBlockStatsUpdateCapacity): Add recursion parameter, although it is ignored for now. * src/qemu/qemu_monitor.h (qemuMonitorGetAllBlockStatsInfo) (qemuMonitorBlockStatsUpdateCapacity): Likewise. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONGetAllBlockStatsInfo) (qemuMonitorJSONBlockStatsUpdateCapacity): Likewise. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONGetAllBlockStatsInfo) (qemuMonitorJSONBlockStatsUpdateCapacity): Add parameter, and split... (qemuMonitorJSONGetOneBlockStatsInfo) (qemuMonitorJSONBlockStatsUpdateCapacityOne): ...into helpers. (qemuMonitorJSONGetBlockStatsInfo): Update caller. * src/qemu/qemu_driver.c (qemuDomainGetStatsBlock): Update caller. * src/qemu/qemu_migration.c (qemuMigrationCookieAddNBD): Likewise.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
