Subject: Re: [PATCH v4 00/13] mm: sub-section memory hotplug support

Hi,
I didn't get to look through the patch series yet and I might not be
able before LSF/MM. How urgent is this? I am primarily asking because
the memory hotplug is really convoluted right now and putting more on
top doesn't really sound like the thing we really want. I have tried to
simplify the code [1] already but this is an early stage work so I do
not want to impose any burden on you. So I am wondering whether this
is something that needs to be merged very soon or it can wait for the
rework and hopefully end up being much simpler in the end as well.

What do you think?
