That won't work. A BO must always outlive the TT object allocated for it.
Otherwise you can get crashes during TT release.
Just my two cents: shouldn't the TT object be increasing Kobj refcount then,
in order to properly manage the BO object lifetime?
No, because you then get a circle reference.
The TT object is usually destroyed when the BO which is referencing it
is destroyed.
