Hi guys!

I finally could test this to see if an old problem reported on bugzilla[1] was
fixed now, but unfortunately it is still there.

The ticket is private I guess, but basically the problem happens when bonding
driver tries to print something after it had taken the write_lock (monitor
functions, enslave/de-enslave), so the printk() will pass through netpoll, then
on bonding again which no matter what mode you use, it will try to read_lock()
the lock again. The result is a deadlock and the entire system hangs.

Does the attached patch fix this hang?

Thanks!

We should notify netconsole that bond is changing its slaves
when we use active-backup mode.
