ksoftirqd/1/18 just changed the state of lock:
0000000068a89c10 (&(&ctx->ctx_lock)->rlock){..-.}, at: spin_lock_irq include/linux/spinlock.h:354 [inline]
0000000068a89c10 (&(&ctx->ctx_lock)->rlock){..-.}, at: free_ioctx_users+0x2d/0x490 fs/aio.c:614
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:
