Subject: [PATCH v9 04/11] drm/shmem: Put booleans in the end of struct drm_gem_shmem_object
Date:   Wed, 23 Nov 2022 05:57:16 +0300
Message-Id: <20221123025723.695075-5-dmitry.osipenko@collabora.com>
In-Reply-To: <20221123025723.695075-1-dmitry.osipenko@collabora.com>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Group all 1-bit boolean members of struct drm_gem_shmem_object in the end
of the structure, allowing compiler to pack data better and making code to
look more consistent.
