This series is RFC as there's pending QEMU work enabling either of the groups:
For the limits the following qemu patches are needed: https://lists.nongnu.org/archive/html/qemu-block/2025-09/msg00804.html For timed stats, the statistics already exist but can't be enabled without: https://lists.nongnu.org/archive/html/qemu-block/2025-10/msg00040.html Patches 1-8 are cleanups and refactors Patches 9-10 extract and expose the block backing file limits. Patches 11-12 extract and expose the timed statistics Patch 13 is qemu capabilities update with the necessary changes and is not to be merged upstream; will be replaced by a proper update. Patches 14-16 add infrastructure to enable timed stats.
