[libvirt] [PATCH 0/1] Fix bogus WWNs

When HBA kernel modules are loaded while libvirt is running, libvirt will often read bogus WWNs from sysfs as at least some modules trigger the HAL event notifying libvirt of adapters' existence before the sysfs info is correct. The following patch causes libvirt to reread the WWNs whenever dumpxml is called so the capability information about the WWNs will be up to date. I pulled the logic to read the WWNs into two separate functions, and the patch is slightly more invasive as a result. The resulting code is smaller and cleaner for it, though, so I think this is the right way to go. (The diff is also very ugly; it should make sense once applied.) Dave
