From 7f340a26f4769a49fb51bfc023ca651dfe16042e Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 30 Mar 2016 11:40:50 +0200 Subject: [PATCH] drm/vgem: Move get_pages to gem_create vgem doesn't have a shrinker or anything like that and drops backing storage only at object_free time. There's no use in trying to be clever and allocating backing storage delayed, it only causes trouble by requiring locking. Instead grab pages when we allocate the object right away. v2: Fix compiling.
