WARNING: possible irq lock inversion dependency detected
5.19.0-syzkaller-02972-g200e340f2196 #0 Not tainted
--------------------------------------------------------
swapper/1/0 just changed the state of lock:
ffff88814a057110 (&group->lock){..-.}-{2:2}, at: snd_pcm_period_elapsed+0x2c/0x210 sound/core/pcm_lib.c:1848
but this lock took another, SOFTIRQ-READ-unsafe lock in the past:
(tasklist_lock){.+.+}-{2:2}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Chain exists of:
&group->lock --> &timer->lock --> tasklist_lock
Possible interrupt unsafe locking scenario:
CPU0 CPU1
---- ----
lock(tasklist_lock);
local_irq_disable();
lock(&group->lock);
lock(&timer->lock);
<Interrupt>
lock(&group->lock);
*** DEADLOCK ***
no locks held by swapper/1/0.
the shortest dependencies between 2nd lock and 1st lock:
-> (tasklist_lock){.+.+}-{2:2} {
