[Qemu-devel] [PATCH v5 00/21] Add qemu-img subcommand to dump file metadata

[Paolo Bonzini]

v4->v5: no change except for context and correcting the "Since: 1.6"
        in qapi-schema.json

Paolo Bonzini (21):
  cow: make reads go at a decent speed
  cow: make writes go at a less indecent speed
  cow: do not call bdrv_co_is_allocated
  block: keep bs->total_sectors up to date even for growable block
    devices
  block: make bdrv_co_is_allocated static
  block: do not use ->total_sectors in bdrv_co_is_allocated
  block: remove bdrv_is_allocated_above/bdrv_co_is_allocated_above
    distinction
  block: expect errors from bdrv_co_is_allocated
  qemu-img: always probe the input image for allocated sectors
  block: make bdrv_has_zero_init return false for copy-on-write-images
  block: introduce bdrv_get_block_status API
  block: define get_block_status return value
  block: return get_block_status data and flags for formats
  block: use bdrv_has_zero_init to return BDRV_BLOCK_ZERO
  block: return BDRV_BLOCK_ZERO past end of backing file
  qemu-img: add a "map" subcommand
  docs, qapi: document qemu-img map
  raw-posix: return get_block_status data and flags
  raw-posix: report unwritten extents as zero
  block: add default get_block_status implementation for protocols
  block: look for zero blocks in bs->file
