I wrote a module and somehow it is corrupting the thread_info of the process.
After some debugging I concluded that its corrupting the kernel stack.
Then I came across Ftrace to get the stack trace, which confirmed high stack usage.

I see around 7K in the depth section of first entry in "stack_trace".
At the same time I run a stap script to get the current stack usage using "stack_used" function.
It comes around 4k.
To my understanding the depth section of first entry in "stack_trace" and value retuned by
stack_used should match.
Is my understanding correct?
Thanks
