So long as the user has some reasonable right to change the affected tasks memory layout, and so long as they are moving memory within the cpuset constraints (if any) of the affected task, or as close to that as practical (such as with ECC soft error avoidance), then yes, it would seem that this sys_migrate_pages() lets existing pages be moved without changing the cpuset policy for the future. -- I won't rest till it's the best ...
