Note: this is a resend - forgot "PATCH" in the subject in
the last mailing.
This is v3 of "block: Modify block-commit to use node-names".
Changes:
* Add Eric's reviewed-by
* Addressed Eric's review comments
* Dropped HMP changes
* Added helper function for setting the overlay, and
set the overlay in bdrv_append()
* Use bs->backing_file instead of bs->backing_hd->filename in block_stream
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
Jeff Cody (12):
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 QMP documentation for block-stream
block: add QAPI command to allow live backing file change
