Subject: [PATCH] conf: Move virDomainObj::originalMemlock into
qemuDomainObjPrivate
Since v1.3.0-90-gafbe1d4c56 the original value of memlock limit
is stored inside virDomainObj struct directly (under
originalMemlock member). This is needless because the value is
used only inside QEMU driver and thus can reside in
qemuDomainObjPrivate struct.
