Re: [Libguestfs] [PATCH nbdkit 0/6] cow: Implement trimming and extents.

I pushed this series, but I made an optimization: In the patch implementing extents, I optimized it so that it asks for the largest ranges possible when querying the plugin. The reason for this is that the VDDK plugin (and probably others too) are very inefficient when you ask them repeatedly for small ranges of extents. Note this patch series is still somewhat experimental (or at least, it's very complex), so if there are any problems with nbdkit-cow-filter please let me know.
