Re: [libvirt] [PATCH 1/1] nodeinfo: Increase the num of CPU thread siblings to a larger value

Current libvirt can only handle up to 1024 thread siblings when it reads Linux sysfs topology/thread_siblings. This isn't enough for Linux distributions that support a large value. This patch fixes the problem by using VIR_ALLOC()/VIR_FREE(), instead of using a fixed-size (1024) local char array. In the meanwhile SYSFS_THREAD_SIBLINGS_LIST_LENGTH_MAX is increased to 8192 which should be large enough for a foreseeable future.
