Re: [libvirt] [PATCH v2 0/2] Enable detection for zero writes

This is a second version with few things fixed. The main difference is that now this series uses zeroes instead of zeros. The latter was chosen at first just because there were more occurences in our codebase, but the former is used now to minimise the confusion -- mainly when none of the versions were used when interfacing with the user or mgmt app. The naming is kept from the previous version despite the discussion as I believe this is pretty general. Also the default value is not changed to 'off' in order for it to be general enough (some hypervisors might choose a different default in the future).
