When a graphics heavy application is running, i915 driver may pin a lot of shmemfs pages and vmscan slows down significantly by scanning these pinned pages. This patch is an alternative to the patch by Chris Wilson [1]. As i915 driver pins all pages in an address space, marking an address space as unevictable is sufficient to solve this issue.
