From f199bf55104d480370515bc736418808e5cfa6b9 Mon Sep 17 00:00:00 2001 From: Matthew Auld Date: Fri, 25 Feb 2022 14:55:01 +0000 Subject: [PATCH] drm/i915/buddy: tweak 2big check MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Otherwise we get -EINVAL, instead of the more useful -E2BIG if the allocation doesn't fit within the pfn range, like with mappable lmem. The hugepages selftest, for example, needs this to know if a smaller size is needed.
