Subject: [Intel-gfx] [PATCH v2 04/11] drm/i915: move intel_context slab to direct module init/exit
Date: Tue, 27 Jul 2021 14:10:30 +0200	[thread overview]
Message-ID: <20210727121037.2041102-4-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210727121037.2041102-1-daniel.vetter@ffwll.ch>

With the global kmem_cache shrink infrastructure gone there's nothing
special and we can convert them over.

I'm doing this split up into each patch because there's quite a bit of
noise with removing the static global.slab_ce to just a
slab_ce.

v2: Make slab static (Jason, 0day)
