From e72bec922646c36e684b42c940f2e3f065147480 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Fri, 18 Jun 2021 21:16:42 +0200 Subject: [PATCH] fuse: ignore PG_workingset after stealing commit b89ecd60d38ec042d63bdb376c722a16f92bcb88 upstream. Fix the "fuse: trying to steal weird page" warning. Description from Johannes Weiner: "Think of it as similar to PG_active. It's just another usage/heat indicator of file and anon pages on the reclaim LRU that, unlike PG_active, persists across deactivation and even reclaim (we store it in the page cache / swapper cache tree until the page refaults). So if fuse accepts pages that can legally have PG_active set, PG_workingset is fine too."
