--------------------------------------------
modprobe/5166 is trying to acquire lock:
ffff8880b9a35bb8 (lock#10){+.+.}-{2:2}, at: local_lock_acquire+0xd/0x170 include/linux/local_lock_internal.h:28
but task is already holding lock:
ffff8880b9a35bb8 (lock#10){+.+.}-{2:2}, at: local_lock_acquire+0xd/0x170 include/linux/local_lock_internal.h:28
other info that might help us debug this:
Possible unsafe locking scenario:

----
lock(lock#10);
lock(lock#10);
*** DEADLOCK ***
May be due to missing lock nesting notation
