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.
