Re: [libvirt] [PATCH 23/23] qemu: block: Add code to detect node names when necessary

Detect the node names when setting block threshold and when reconnecting or when they are cleared when a block job finishes. This operation will become a no-op once we fully support node names. --- src/qemu/qemu_block.c | 98 ++++++++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_block.h | 4 ++ src/qemu/qemu_blockjob.c | 2 + src/qemu/qemu_driver.c | 5 +++ src/qemu/qemu_process.c | 4 ++ 5 files changed, 113 insertions(+)
