Subject: [PATCH] tracing: Fix typo in comments, print info and function
Date:   Fri, 30 Jul 2021 14:15:04 +0800
Message-ID: <20210730061504.2687-1-caihuoqing@baidu.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Fix typo:
*singe  ==> single
*outputing  ==> outputting
*ingore  ==> ignore
*preapre  ==> prepare
*overlayed  ==> overlaid
*alloced  ==> allocated
*varaibles  ==> variables
*timestemp  ==> timestamp
*reseted  ==> reset
*overwite  ==> overwrite
