Subject: [PATCH] fs: wipe off the compiler warn
Date: Fri, 29 Jul 2016 22:45:01 +0800 [thread overview]
Message-ID: <1469803501-44148-1-git-send-email-zhongjiang@huawei.com> (raw)
From: zhong jiang <zhongjiang@huawei.com>
when compile the kenrel code, I happens to the following warn.
fs/reiserfs/ibalance.c:1156:2: warning: ‘new_insert_key’ may be used
uninitialized in this function.
memcpy(new_insert_key_addr, &new_insert_key, KEY_SIZE);
^
The patch just fix it to avoid the warn.
