From: Chris Wilson Date: Tue, 7 Nov 2017 11:05:59 +0000 Subject: drm/i915/selftests: Skip mixed page exhaustion if only small pages available Git-commit: f6d03042b9ad514077175b5cc53069e0a364d0ec Patch-mainline: v4.16-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 If we only have 4k pages, we can't mix together different combinations of hugepages to see if the world burns. However, as the loops did nothing, we never set err to 0 and reported ENODEV aborting the test. Teach the test to skip instead.
