Sample crash report:
========================================================
WARNING: possible irq lock inversion dependency detected
5.6.0-syzkaller #0 Not tainted
--------------------------------------------------------
syz-executor941/7000 just changed the state of lock:

ffff88808d9b18d8 (&info->lock){+.+.}-{2:2}, at: shmem_mfill_atomic_pte+0x13f4/0x1e10 mm/shmem.c:2402
but this lock was taken by another, SOFTIRQ-safe lock in the past:
 (&xa->xa_lock#4){..-.}-{2:2}


and interrupts could create inverse lock ordering between them.


other info that might help us debug this:
 Possible interrupt unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
