[libvirt] [PATCH v4 12/14] nodedev: Convert virNodeDeviceObj to use virObjectLockable
John Ferlan
jferlan at redhat.com
Mon Jul 3 21:25:28 UTC 2017
Now that we have a bit more control, let's convert our object into
a lockable object and let that magic handle the create and lock/unlock.
This also involves creating a virNodeDeviceEndAPI in order to handle
the object cleaup for API's that use the Add or Find API's in order
to get a locked/reffed object. The EndAPI will unlock and unref the
object returning NULL to indicate to the caller to not use the obj.
For now this also involves a forward reference to the Unlock, but
that'll be removed shortly when the object is convert to use the
virObjectLockable shortly.
