[libvirt] [PATCH v3 00/18] Converge Storage Pool vHBA logic with Node Device

v2: http://www.redhat.com/archives/libvir-list/2017-March/msg00161.html Changes since v2: - Pushed the former patch1 after a slight adjustment replace a spurrious lost line - [NEW] Patch 1 - Fixes an existing bug - details in patch - [UPD] Patch 2 - Split out what Jano noted about new checks into it's own - [UPD] Patch 3->14 - Rework the former patch2 to split out the step by step details it took to get to patch2. - [No Change] Patch 15-18 -> Patch15->16 ACKed in v1, but I just left these in the order I had -> Patch17->18 Unchanged - same comment as v2 (copied so as to not force someone would go back to v2): Even though there is concern over usage of API's in this manner (e.g. calling virNodeDeviceLookupSCSIHostByWWN as well as virNodeDeviceCreateXML) - the "purpose" of the exercise is a means to have the StoragePool code use the same algorithms as the node device code instead of what could be a potentially long slow journey through the sysfs file system. The key piece being the replication of the API's that find the parent in the node device object list. I suppose it would be possible to add even more API's to get that answer, but I'm not sure it'd be worthwhile at this point. As for the concern about deadlock - I understand it, but since the whole purpose of the API is to essentially utilize the nodedev create algorithm there'd be no reason for nodedev to call it. If it doesn't get ACK'd - that's OK - I can hold onto it and reconsider some other means at some point in time in the future (probably distant future too).
