Subject: drm/i915: Rework __i915_gem_shrink
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=80dcfdbd68b094f21f7ce222fb8039123f5b4cbe;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: Rework __i915_gem_shrink

In order to do this for all VMs, it's convenient to rework the logic a
bit. This should have no functional impact.
