From 078b7de41249b989a574339078696663e095cf37 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 2 Nov 2018 14:25:42 +0100 Subject: [PATCH] drm/file: Uncompact the feature flags This essentially undoes commit 39868bd7668bd47308b1dfd97c212757caee764f Author: Chris Wilson Date: Tue Oct 29 08:55:58 2013 +0000 drm: Compact booleans within struct drm_file We do lockless access to these flags everywhere, and it's kinda not a great idea to mix lockless and bitfields. Aside from that gcc isn't generating great code for these. If this ever becomes an issue size-wise, I think we need atomic_t here and atomic bitflag ops.
