From: Chris Wilson Date: Fri, 9 Jun 2017 11:03:48 +0000 (+0100) Subject: drm/i915: Only restrict noreclaim in the early shrink passes X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f6ab55d7ab6847e9b799022ed3b5511c756e512;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Only restrict noreclaim in the early shrink passes In our first pass, we do not want to use reclaim at all as we want to solely reap the i915 buffer caches (its purgeable pages). But we don't mind it initiates IO or pulls via the FS (but it shouldn't anyway as we say no to reclaim!). Just drop the GFP_IO constraint for simplicity.
