Subject: Re: [PATCH v3 net-next 2/2] net: dsa: qca: ar9331: export stats64
Hello Jakub and Andrew,
> Ah, I missed the v3 (like most reviewers it seems :)).
No problem, I moved your replies from v2 tread to this mail.

I added dump_stack() to the stats64 function, so we can see how it is
used.

stats are automatically read on __dev_notify_flags(), for example here:

Do we really need an extra read within the ar9331 driver?

Yes. And underling layer is mdio bus which is by default sleeping as
well.
> Am I missing something?
In this log, the ar9331_get_stats64() was never called from atomic or
irq context. Why it should not be sleeping?
