Hi Steffen,

I did not have the time to test and send a v2 for my patch to remove the leftover local_bh_disable()/local_bh_enable() Ben has spotted.
I've also tried to use your approach but in my tests, under high load, the defered work was defered forever...

I'll try to test again with your patch and confirm it does not suffer from this issue or send a patch with those local_bh removed.

Is there any progress in fixing this issue? I've seen this occasionally on some of our production systems, so I fixed it for us in the meantime with the patch below. I could submit this for inclusion if noone else wants to fix it in a different manner.
