[libvirt] [PATCH 20/25] qemu: Introduce qemuBuildRedirdevCommandLine

Add new function to manage adding the redirdev device options to the command line removing that task from the mainline qemuBuildCommandLine. Also move the qemuBuildRedirdevDevStr closer to the new function and modify to use the const virDomainDef instead of virDomainDefPtr Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- src/qemu/qemu_command.c | 243 +++++++++++++++++++++++++----------------------- src/qemu/qemu_command.h | 2 +- 2 files changed, 129 insertions(+), 116 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index af09e1e..0649d72 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -4166,93 +4166,6 @@ qemuBuildPCIHostdevPCIDevStr(virDomainHostdevDefPtr dev, char * -qemuBuildRedirdevDevStr(virDomainDefPtr def, - virDomainRedirdevDefPtr dev, - virQEMUCapsPtr qemuCaps) -{ - size_t i;
