Subject: [PATCH] conf: Move virDomainObj::originalMemlock into
11fcb6
 qemuDomainObjPrivate
11fcb6
11fcb6
Since v1.3.0-90-gafbe1d4c56 the original value of memlock limit
11fcb6
is stored inside virDomainObj struct directly (under
11fcb6
originalMemlock member). This is needless because the value is
11fcb6
used only inside QEMU driver and thus can reside in
11fcb6
qemuDomainObjPrivate struct.
