From e8351ac9bfa7f4412d5d196b6742309473ca506d Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Tue, 21 Jan 2014 15:49:52 -0800 Subject: mm/rmap: use rmap_walk() in try_to_munlock() Now, we have an infrastructure in rmap_walk() to handle difference from variants of rmap traversing functions. So, just use it in try_to_munlock(). In this patch, I change following things. 1. remove some variants of rmap traversing functions. cf> try_to_unmap_ksm, try_to_unmap_anon, try_to_unmap_file 2. mechanical change to use rmap_walk() in try_to_munlock(). 3. copy and paste comments.
