Date: Fri, 16 Jan 2015 08:50:51 -0500 From: Rafael Aquini <aquini@...hat.com> To: linux-kernel@...r.kernel.org Cc: akpm@...ux-foundation.org, jweiner@...hat.com, dave.hansen@...ux.intel.com, rientjes@...gle.com, linux-mm@...ck.org Subject: [PATCH 2/2] fs: proc: task_mmu: bump kernelpagesize_kB to EOL in /proc/pid/numa_maps Commit "4dd025c fs: proc: task_mmu: show page size in /proc/<pid>/numa_maps" (linux-next) introduces 'kernelpagesize_kB' to numa_maps proc interface. This patch, per Andrew Morton suggestion, switchs 'kernelpagesize_kB' position to EOL in /proc/<pid>/numa_maps to potentially avoid causing trouble to any existent parser that expects numa_maps file line previous layout.
