Re: [libvirt] [PATCH 08/17] conf: give each hostdevdef a parent pointer

The parent can be any type of device. It defaults to type=none, and a NULL pointer. The intent is that if a hostdevdef is contained in the def for a higher level device (e.g. virDomainNetDef), hostdev->parent will point to the higher level device, and type will be set to that type of device. This way, during attach and detach of the device, parent can be checked, and appropriate callouts made to do higher level device initialization (e.g. setting MAC address). Also, although these hostdevs with parents will be added to a domain's hostdevs list, they will be treated slightly differently when traversing the list, e.g. virDomainHostdefDefFree for a hostdev that has a parent doesn't need to be called (and will be a NOP); it will simply be removed from the list (since the parent device object is in its own type-specific list, and will be freed from there). --- V2: unchanged from V1 src/conf/domain_conf.c | 12 ++++++++++-- src/conf/domain_conf.h | 1 + 2 files changed, 11 insertions(+), 2 deletions(-)
