From 18863d3a3f593f47b075b9f53ebf9228dc76cf72 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Wed, 3 May 2017 14:54:04 -0700 Subject: mm: remove SWAP_DIRTY in ttu If we found lazyfree page is dirty, try_to_unmap_one can just SetPageSwapBakced in there like PG_mlocked page and just return with SWAP_FAIL which is very natural because the page is not swappable right now so that vmscan can activate it. There is no point to introduce new return value SWAP_DIRTY in try_to_unmap at the moment.
