Subject: [PATCH] mm/mmap.c: Remove useless statement "vma = NULL" in find_vma()
Date: Thu, 3 Sep 2015 11:52:26 +0800 [thread overview]
Message-ID: <1441252346-2323-1-git-send-email-gang.chen.5i5j@gmail.com> (raw)
From: Chen Gang <gang.chen.5i5j@gmail.com>
Before the main looping, vma is already is NULL, so need not set it to
NULL, again.
