Hello,

Is anyone working on block filters?  If so, can you please tell me what the 
current progress is?  I am referring to item "BlockFilter and dynamic 
reconfiguration of the BDS graph" on the to-do list [1].

Thanks for your time,

Hello,

1) I once wanted to write block filters.
2) I am not a QEMU contributor anymore.
3) If you need block filters you also need to write them.

Best regards

Benoît
