We're discussing a change in the memory.rst on suggested way to use dynamic
MRs, so I think we can do it in one shot rather than making it confusing.
It's not a huge change even in one go.

It's fine.  You're right we can remove the object_unparent() first when
it's always a no-op.  We'll update the doc twice, though I assume it's fine.

If you would, please consider sending this part as a separate series.

The subject should be something like "remove unnecessary object_unparent()
for dynamic MRs" or something like that.  It has nothing to do with
memleaks on this part.

Please cover tests as much as possible and if we touch the doc we need to
convert everything that uses dynamic MRs, including the missing ones in
VFIO, and also the rest occurances.

Thanks,
