From 92be775a3db343889ab159c44d55315c5ee0be4e Mon Sep 17 00:00:00 2001 From: Kirill Tkhai Date: Tue, 21 Aug 2018 21:51:53 -0700 Subject: mm: struct shrink_control: keep int fields together Patch series "Reorderings in struct shrinker and struct shrink_control". These structures are intensively used during reclaim and, displace other data in cache, so there is no a reason they have int fields not grouped together. This patch (of 2): gfp_t is of unsigned type, so let's move nid to keep them together.
