Hi, I find if I use a defined stack size to create a child thread,
then the max stack size from /proc/pid/task/child pid/limits still
shows "Max stack size            8388608", it doesn't update to
the user defined size, is it a problem?

This reflects the maximum stack size of the main thread after execve. 
The size of the stack of the current thread is a separate matter; it can 
be located anywhere in the process image and much smaller or larger than 
the maximum size of the initial stack of the main thread.

Thanks,
