Currently, when there is an API that's blocking with locked domain and second API that's waiting in virDomainObjListFindByUUID() for the domain lock (with the domain list locked) no other API can be executed on any domain on the whole hypervisor because all would wait for the domain list to be locked. This patch adds new optional approach to this in which the domain is only ref'd (reference counter is incremented) instead of being locked and is locked *after* the list itself is unlocked. We might consider only ref'ing the domain in the future and leaving locking on particular APIs, but that's no tonight's fairy tale.Signed-off-by: Martin Kletzander <mklet...@redhat.com> --- v2: - rebased on master where searching for domains was changed - there's a difference between virDomainObjListFindByUUID and virDomainObjListFindByUUIDRef now! src/conf/domain_conf.c | 29 ++++++++++++++++++++++++++--- src/conf/domain_conf.h | 2 ++ src/libvirt_private.syms | 1 + 3 files changed, 29 insertions(+), 3 deletions(-)
