From f6c6010a07734103a31faa0cc977641b358c45b0 Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Tue, 5 Mar 2019 16:34:32 +0800 Subject: mm/resource: Use resource_overlaps() to simplify region_intersects() The three checks in region_intersects() are basically an open-coded version of resource_overlaps() - so use the real thing. Also fix typos in comments while at it.
