Your find has encountered /proc/sys/vm/scan_unevictable_pages and reading that file triggers the above warning which has been added to warn people that this file would go away. This has actually happened in 3.18 (1f13ae399c58 "mm: remove noisy remainder of the scan_unevictable interface"). > this is why I am sending this email. how can I solve this message ? You do not have to care about it at all because you weren't reading that file to get a "reasonable" value. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
