[Qemu-devel] [PATCH 00/10] block/json: Add JSON protocol driver

[Max Reitz <mreitz@redhat.com>]

This series adds a passthrough JSON protocol block driver. Its filenames
are JSON objects prefixed by "json:". The objects are used as options
for opening another block device which will be the child of the JSON
device. Regarding this child device, the JSON driver behaves nearly the
same as raw_bsd in that it is just a passthrough driver. The only
difference is probably that the JSON driver identifies itself as a block
filter, in contrast to raw_bsd.

The purpose of this driver is that it may sometimes be desirable to
specify options for a block device where only a filename can be given,
e.g., for backing files. Using this should obviously be the exception,
but it is nice to have if actually needed.


Max Reitz (10):
  qdict: Add qdict_join()
  block/json: Add JSON protocol driver
  block/json: Add functions for cache control
  block/json: Add functions for writing zeroes etc.
  block/json: Add bdrv_co_get_block_status()
  block/json: Add ioctl etc.
  block/json: Add bdrv_get_specific_info()
  block/raw_bsd: Add bdrv_get_specific_info()
  block/qapi: Ignore filters on top for format name
  iotests: Add test for the JSON protocol
