From cdf7b3418ad5a8783efe8f9124023d9b869fec0f Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Mon, 21 Sep 2009 17:03:36 -0700 Subject: [PATCH] mmap: remove unnecessary code If (flags & MAP_LOCKED) is true, it means vm_flags has already contained the bit VM_LOCKED which is set by calc_vm_flag_bits(). So there is no need to reset it again, just remove it.
