[PATCH 1/1] tracing: fix spelling mistakes

From: Zhen Lei
Date: Tue May 25 2021 - 02:21:15 EST


Fix some spelling mistakes in comments:
wont ==> won't
overwite ==> overwrite
outputing ==> outputting
overlayed ==> overlaid
singe ==> single

The name of an unused function parameter:
ingore ==> ignore

And the name of the cpuhp step:
preapre ==> prepare

but it does cause an unwanted overhead. Enabling this option will
place where recursion was detected into the ftrace "recursed_functions"
file.
