[Qemu-block] [PATCH v2 00/21] block: Cache mode for children etc.

Subject: [Qemu-block] [PATCH v2 00/21] block: Cache mode for children etc.

This is part three (or four, depending on whether you count the bdrv_swap
removal) of what I had sent earlier as "[PATCH 00/34] block: Cache mode for
children, reopen overhaul and more". Most of the patches were actually already
reviewed in v1.

This part contains the remaining functional changes that the cover letter for
v1 advertised, and a bit more:

- You can now use node name references for backing files
- bdrv_reopen() works now properly for inherited options (don't exist before
  this series; after the series the cache options)
- bdrv_reopen() works now properly with semantically overlapping options
- bdrv_reopen() can change child node options
- And finally you can set cache mode options for backing files and other
  children now (and the reopen behaviour even makes sense

Kevin Wolf (21):
  qcow2: Add .bdrv_join_options callback
  block: Fix reopen with semantically overlapping options
  mirror: Error out when a BDS would get two BBs
  block: Allow references for backing files

  block: Exclude nested options only for children in
  block: Pass driver-specific options to .bdrv_refresh_filename()
  block: Keep "driver" in bs->options
  block: Allow specifying child options in reopen
  block: reopen: Document option precedence and refactor accordingly
  block: Add infrastructure for option inheritance
  block: Split out parse_json_protocol()
  block: Introduce bs->explicit_options
  blockdev: Set 'format' indicates non-empty drive
  qemu-iotests: Remove cache mode test without medium
  block: reopen: Extract QemuOpts for generic block layer options
  block: Move cache options into options QDict
  blkdebug: Enable reopen
  qemu-iotests: Try setting cache mode for children
  qemu-iotests: Test cache mode option inheritance
