[PATCH v2 0/3] mm: Fix memory block leaks and locking

[Muchun Song]

This series fixes two memory block device reference leaks and one
locking issue around the per-memory_block hwpoison counter.

Changes in v2:
- Add Acked-by from Oscar Salvador to patch 1.
- Keep the series as pure bug fixes; defer
  memory_block_get_by_id()/memory_block_put cleanup to a separate
  series.
- Add Reviewed-by from Miaohe Lin to patch 2.
- Add device_hotplug_lock handling in patch 3.

Muchun Song (3):
  mm/memory_hotplug: fix memory block reference leak on remove
  drivers/base/memory: fix memory block reference leak in poison
    accounting
  drivers/base/memory: fix locking for poison accounting lookup
