Subject[PATCH] move_pages.2: not return ENOENT if the page are already on the target nodes
Date
Since commit e78bbfa82624 ("mm: stop returning -ENOENT
from sys_move_pages() if nothing got migrated"), move_pages doesn't
return -ENOENT anymore if the pages are already on the target nodes, but
this change is never reflected in manpage.
