[libvirt] [PATCH 07/12] libxl: Introduce libxlDriverConfig object
Jim Fehlig

Fri Aug 30 21:46:53 UTC 2013
The libxlDriverPrivate struct contains an variety of data with
varying access needs. Similar to the QEMU and LXC drivers,
move all the static config data into a dedicated libxlDriverConfig
object. The only locking requirement is to hold the driver lock
while obtaining an instance of libxlDriverConfig. Once a reference
is held on the config object, it can be used completely lockless
since it is immutable.
