WARNING: possible irq lock inversion dependency detected

--------------------------------------------------------
syz-executor.5/27483 just changed the state of lock:
ffff0001083e9430 (k-slock-AF_INET#2){+.-.}-{2:2}, at: spin_lock include/linux/spinlock.h:350 [inline]

but this lock took another, SOFTIRQ-unsafe lock in the past:
 (k-clock-AF_INET){+++.}-{2:2}


and interrupts could create inverse lock ordering between them.


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