WARNING: possible irq lock inversion dependency detected
5.15.0-rc5-syzkaller #0 Not tainted
--------------------------------------------------------
syz-executor.1/17246 just changed the state of lock:
ffffffff8d17ad38 (nl_table_lock){.+.?}-{2:2}, at: __netlink_diag_dump+0x2ce/0x790 net/netlink/diag.c:155
but this lock was taken by another, SOFTIRQ-safe lock in the past:
(&local->queue_stop_reason_lock){..-.}-{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
---- ----
lock(nl_table_lock);
local_irq_disable();
lock(&local->queue_stop_reason_lock);
lock(nl_table_lock);
