From: Ben Widawsky Date: Wed, 31 Jul 2013 23:59:57 +0000 (-0700) Subject: drm/i915: Use bound list for inactive shrink X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fcb4a57805e04dee04f736c25a5648ec7bebe30f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: Use bound list for inactive shrink Do to the move active/inactive lists, it no longer makes sense to use them for shrinking, since shrinking isn't VM specific (such a need may also exist, but doesn't yet). What we can do instead is use the global bound list to find all objects which aren't active.
