[Qemu-devel] [PATCH V17 00/12] quorum block filter

["Benoît Canet" <benoit.canet@irqsave.net>]

I post this for review in prevision of 2.0 feature freeze.
Even if the series look correct please wait before merging because:

The QMP events in the "Add quorum mechanism" definitively needs to be reviewed
by Eric as they where changed.

I did not found any bugs while testing this version but I am willing to test the
code further before it's applied even it's reviewed by.

Best regards

Benoît
