I would like to start discussion about balancing the occupancy of memory zones in a node in the system whose imabalance may be caused by migration of pages to other zones during hotremove and then hotadding same memory. In this case there is a lot of free memory in newly hotadd memory which can be filled up by the previous migrated pages(as part of offline/hotremove) thus may free up some pressure in other zones of the node.
Why is this specific to memory hot(un)plug? I think the problem is more generic:
Assume 1. Application 1 allocates a lot of memory and gets ZONE_MOVABLE. 2. Application 2 allocates a lot of memory and gets ZONE_NORMAL. 3. Application 1 quits. Same problem, no? -- Thanks, David / dhildenb
