ksoftirqd/0/9 just changed the state of lock:

kobject: 'loop2' (00000000fa163a68): fill_kobj_path: path = '/devices/virtual/block/loop2'
but this lock took another, SOFTIRQ-unsafe lock in the past:
(&fiq->waitq){+.+.}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:
