dtbo img is not compiled, the reason for this is python2;

Python2 is not supported in new Linux operating systems and this version is older than Python3.

To solve the error, I am ported the mkdtboimg file to Python3.

UPSTREAM: net: bpfilter: use get_pid_task instead of pid_task
b6f2fc3 
pid_task() dereferences rcu protected tasks array.
But there is no rcu_read_lock() in shutdown_umh() routine so that
rcu_read_lock() is needed.
get_pid_task() is wrapper function of pid_task. it holds rcu_read_lock()
then calls pid_task(). if task isn't NULL, it increases reference count
of task.

test commands:
   %modprobe bpfilter
   %modprobe -rv bpfilter
