It's a false positive introduced in 2.6.34 by the inode shrinker.
That's one of several different false positive traces in 2.6.34,
but I can't do anything about them because the shrinkers require
global scope. The patches to customise the shrinker contexts (which
avoids all of these warnings) will fix this....
You may as well not run lockdep on anything with an XFS filesystem,
as these false positives will occur as soon as memory reclaim
triggers and turn lockdep off.
Cheers,
Dave.

Fix a lockdep-splat-causing regression introduced by

:
: fasync: RCU and fine grained locking
kill_fasync() can be called from both process and hard-irq context, so
fa_lock must be taken with IRQs disabled.

Sorry for the delay, I was travelling...
Alternative solution would be to change fasync_remove_entry() and
fasync_add_entry() to use spin_lock_irq(&fasync_lock) and
spin_lock(&fa->fa_lock), but we would disable IRQ on possibly long scans
(as before my "fasync: RCU and fine grained locking" patch).

I don't understand this code, but at first glance drivers/net/r8169.c
is obviously buggy.
The work->func, rtl8169_reset_task(), calls rtl8169_rx_interrupt() ->
netif_receive_skb(), and the last one may only be called from softirq.

Yes, this is wrong. In this context (process context, not softirq), we
should use netif_rx() or just drop frames if we are in reset phase.
Also, this driver schedules a reset in case a fifo error is reported in
rtl8169_rx_interrupt()
if (status & RxFOVF) {
rtl8169_schedule_work(dev, rtl8169_reset_task);
dev->stats.rx_fifo_errors++;
}
This seems very strange too : In case of a RX spike, we reset card ?

It's possible that this has been found to hang the card.
If so, it should be documented because otherwise yes we
should not be doing this.
