From 3b96d7db3b6dc99d207bca50037274d22e48dea5 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Thu, 23 Jan 2014 15:55:58 -0800 Subject: [PATCH] fs/exec.c: call arch_pick_mmap_layout() only once Currently both setup_new_exec() and flush_old_exec() issue a call to arch_pick_mmap_layout(). As setup_new_exec() and flush_old_exec() are always called pairwise arch_pick_mmap_layout() is called twice. This patch removes one call from setup_new_exec() to have it only called once.
