[RFC PATCH 0/5] qemu: Stop using 'raw' driver when not needed

This patchset is RFC as it requires qemu patches to preserve format inside the 'backing file format' field, or we could break qcow2 images for older libvirt. The main rationale is documented in 5/5. Peter Krempa (5): [DO NOT PUSH] update qemu capabilities for 'backing-mask-protocol' qemu: capabilities: Introduce QEMU_CAPS_BLOCKJOB_BACKING_MASK_PROTOCOL qemu: monitor: Use 'backing-mask-protocol' for blockjobs when available qemu: block: Always add extra 'raw' layer for storage slice qemuBlockStorageSourceNeedsFormatLayer: Stop formatting 'raw' driver when not needed src/qemu/qemu_block.c | 66
