[Qemu-devel] [PATCH v2 00/11] Modify block jobs to use node-names

[Jeff Cody]

This is based on Fam's "Drop in_use with op_blocker" series.

This is v2 of "block: Modify block-commit to use node-names", but with
additional changes.  Changes include new functionality (helper functions,
block-stream changes, new QAPI command), as well as review comments from
Benoit, and Eric.

Using node-names instead of filenames for block job operations
over QMP is a superior method of identifying the block driver
images to operate on, as it removes all pathname ambiguity.

This series modifies block-commit and block-stream to use node-names,
and creates a new QAPI command to allow stand-alone backing file
changes on an image file.

So that node-names can be used as desired for all block job
operations, this series also auto-generates node-names for every
BDS.  User-specified node-names will override any autogenerated
node-names.


Jeff Cody (11):
  block: Auto-generate node_names for each BDS entry
  block: add helper function to determine if a BDS is in a chain
  block: Add overlay BDS pointer into the BlockDriverState struct
  block: add helper function to find the active layer of any BDS
  block: simplify bdrv_find_base()
  block: make 'top' argument to block-commit optional
  block: Accept node-name arguments for block-commit
  block: extend block-commit to accept a string for the backing file
  block: add ability for block-stream to use node-name
  block: add backing-file option to block-stream
  block: add QAPI command to allow live backing file change
