Locked pages are those, protected by mlock() or IPC_LOCK.
These are rarely used, but if an application locks the page, it becomes unreclaimable and unswappable, so this resource should be controlled for sure.

locked pages are usually used in security software to make sure that page won't be dropped from memory to swap etc. and password won't be foundable in swap file Smile
