>From f19c414860a1231460cd3380a7a15f6fb630ef64 Mon Sep 17 00:00:00 2001 From: Daeseok Youn <daeseok.youn@xxxxxxxxx> Date: Thu, 28 Nov 2013 10:52:03 +0900 Subject: [PATCH] kernel/fork.c : remove redundant NULL check in dup_mm() current->mm doesn't need to check NULL in dup_mm(). Becasue dup_mm() is used only in copy_mm() and current->mm is checked whether it is NULL or not in copy_mm() before calling dup_mm().
