Subject: [PATCH] [BZ 156627] chmem: try to online memory to zone movable
|
|
From: Gerald Schaefer <gerald.schaefer@de.ibm.com>
|
|
|
|
Description: chmem: try to online memory to zone movable
|
|
Symptom: Standby/reserved memory that is onlined with chmem will be set
|
|
online to zone normal, instead of zone movable, and so it is much
|
|
less likely to be able to be offlined again.
|
|
Problem: With recent kernels, the default zone for hotplug memory was
|
|
changed from zone movable to zone normal.
|
|
Solution: Let chmem first try to online memory to the zone movable, before
|
|
setting it online to the default zone.
|
|
Reproduction: Set standby/reserved memory online with chmem, and check
|
|
/proc/zoneinfo for zone allocation.
