From 9de4f22a60f731943f050f4448bf2933ed3fa70b Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Mon, 6 Apr 2020 20:04:41 -0700 Subject: mm: code cleanup for MADV_FREE Some comments for MADV_FREE is revised and added to help people understand the MADV_FREE code, especially the page flag, PG_swapbacked. This makes page_is_file_cache() isn't consistent with its comments. So the function is renamed to page_is_file_lru() to make them consistent again. All these are put in one patch as one logical change.
