Re: [libvirt] [PATCH 0/7] Adjustments for storage/qemu volume/file backing size settings

A bit of a mix between fixing some bugs and merging some code between the block info/stats fetching of backing store data and storage backend data for volume allocation, capacity, and physical sizes. Patch 1 just adjusts some comments Patches 2-3 are code motion Patch 4 alters how domain/qemu will open the backing store from an open to a qemuFileOpen and it allows for fetching of more physical sizes (the code only gets the block backing stores now) Patch 5 shares the setting of the various size values between storage driver and domain/qemu Patch 6 shares the recalculation of the capacity value (it may not be necessary for patch 5, but I left it there since there's multiple other paths to the VolTargetInfoFD API). Patch 7 fixes an issue with displaying the allocation value of a qcow2 backed file for the GetBlockInfo API (the results will match volume code now).
