[PATCH 2/2] dax/kmem: Update spanned page stat of origin device node

When device memory adds to the online NUMA node, the number of spanned pages of the original device NUMA node should be updated. By this patch, we can monitor the current spanned pages of each node more accurately. Signed-off-by: Jonghyeon Kim --- drivers/dax/kmem.c | 14 ++ 1 file

[PATCH 1/2] mm/memory_hotplug: Export shrink span functions for zone and node

Export shrink_zone_span() and update_pgdat_span() functions to head file. We need to update real number of spanned pages for NUMA nodes and zones when we add memory device node such as device dax memory. Signed-off-by: Jonghyeon Kim --- include/linux/memory_hotplug.h | 3 +++
