Subject: [PATCH 2/3] drm/file: Uncompact the feature flags
Date: Fri,  2 Nov 2018 14:25:42 +0100	[thread overview]
Message-ID: <20181102132543.16486-2-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20181102132543.16486-1-daniel.vetter@ffwll.ch>

This essentially undoes

commit 39868bd7668bd47308b1dfd97c212757caee764f
Author: Chris Wilson <chris@chris-wilson.co.uk>

    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.
