[PATCH RFCv1 0/5] mm/memory_hotplug: selective merging of memory resources
Some add_memory*() users add memory in small, contiguous memory blocks.
Examples include virtio-mem, hyper-v balloon, and the XEN balloon.
This can quickly result in a lot of memory resources, whereby the actual
resource boundaries are not of interest (e.g., it might be relevant for
DIMMs, exposed via /proc/iomem to user space). We really want to merge
added resources in this scenario where

[PATCH v2 0/6] mm / virtio-mem: support ZONE_MOVABLE
@Andrew, @Mst, I suggest the whole series (including the virtio-mem
change) goes via the -mm tree.
Currently, virtio-mem does not really support ZONE_MOVABLE. While it allows
to online fully plugged memory blocks to ZONE_MOVABLE, it does not allow
to online partially-plugged memory blocks to ZONE_MOVABLE and will never
consider such memory blocks when unplugging memory. This might be
surprising

[PATCH v5 0/6] mm / virtio-mem: support ZONE_MOVABLE
For 5.10. Patch #1-#4,#6 have RBs or ACKs, patch #5 is virtio-mem stuff
maintained by me. This should go via the -mm tree.
---
When introducing virtio-mem, the semantics of ZONE_MOVABLE were rather
unclear, which is why we special-cased ZONE_MOVABLE such that partially
plugged blocks would never end up in ZONE_MOVABLE.
Now that the semantics are much clearer (and are documented in patch #6),

[PATCH v4 0/6] mm / virtio-mem: support ZONE_MOVABLE
@Andrew can we give this a churn and consider it for v5.9 in case there
are no more comments?

by me (and MST is aware).
