[libvirt] [PATCH 0/4] qemu: Don't use API flags in monitor code (blockdev-add saga)
Peter Krempa (4): qemu: migration: Don't pass around flags for different API qemu: monitor: Don't pass full flags to qemuMonitorJSONBlockdevMirror qemu: monitor: Don't pass full flags to qemuMonitorJSONDriveMirror qemu: monitor: Use VIR_AUTOPTR in qemuMonitorJSON(Drive/Blockdev)Mirror src/qemu/qemu_driver.c | 4 +- src/qemu/qemu_migration.c | 21 ++++------ src/qemu/qemu_monitor.c | 17 ++++---- src/qemu/qemu_monitor.h | 5 ++- src/qemu/qemu_monitor_json.c | 79 ++++++++++++++---------------------- src/qemu/qemu_monitor_json.h | 5 ++- tests/qemumonitorjsontest.c | 6 +-- 7 files changed, 60 insertions(+), 77 deletions(-) -- 2.21.0
The NBD migration code uses drive/blockdev-mirror internally. In those APIs we pass around flags for the monitor commands which are based on the flags for the virDomainBlockRebase API. Since there's only one flag which changes, pass it around explicitly rather than obscuring it in a bitfield.
