From 2a23f2b8adbe4bd584f936f7ac17a99750eed9d7 Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Mon, 27 Aug 2018 18:29:29 +0300 Subject: fuse: use READ_ONCE on congestion_threshold and max_background Since they are of unsigned int type, it's allowed to read them unlocked during reporting to userspace. Let's underline this fact with READ_ONCE() macroses.
