[Qemu-devel] [PATCH 0/5] block: Modify block-commit to use node-names

[Jeff Cody <jcody@redhat.com>]

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 is the conversion of block-commit to allow use of
node-names.  Also, it allows the user to specify the string for
the backing_file name to use in the overlay image.

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.

Subsequent patches will convert the remaining block operations
(stream, backup, mirror)

Jeff Cody (5):
  block: Auto-generate node_names for each BDS entry
  block: add helper function to determine if a BDS is in a chain
  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
