Subject: [PATCH] tracing: Fix typo in comments, print info and function
Fix typo:
*singe ==> single
*outputing ==> outputting
*ingore ==> ignore
*preapre ==> prepare
*overlayed ==> overlaid
*alloced ==> allocated
*varaibles ==> variables
*timestemp ==> timestamp
*reseted ==> reset
*overwite ==> overwrite
