Subject[PATCH 0/2] shmem, drm/i915: Mark pinned shmemfs pages as unevictable
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.


Kuo-Hsin Yang (2):
shmem: export shmem_unlock_mapping
drm/i915: Mark pinned shmemfs pages as unevictable
