Subject: [PATCH] move_pages.2: not return ENOENT if the page are already on the target nodes
Date: Fri,  6 Dec 2019 09:34:50 +0800	[thread overview]
Message-ID: <1575596090-115377-1-git-send-email-yang.shi@linux.alibaba.com> (raw)

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.
